How much time is in each quarter of an American football game?
American football
Football games last for a total of 60 minutes in professional and college play and are divided into two-halves of 30 minutes and four-quarters of 15 minutes. High school football games are 48 minutes in length with two-halves of 24 minutes and four-quarters of 12 minutes. The two-halves are separated by a halftime period, and the first and third quarters are also followed by a short break. Prior to the start of the game, the referee and team captains for each team meet at midfield for a coin toss. The visiting team is allowed to call 'heads' or 'tails'; the winner of the toss is allowed to decide between choosing whether to receive or kick off the ball or choosing which goal they want to defend, but they can also defer their choice until the second half. The losing team, unless the winning team decides to defer, is allowed to choose the option the winning team did not select, and receives the option to receive, kick, or select a goal to defend to begin the second half. Most teams choose to receive or defer, because choosing to kick the ball to start the game would allow the other team to choose which goal to defend. Teams switch goals following the first and third quarters. If a down is in progress when a quarter ends, play continues until the down is completed.

The methods of scoring are:Resumption of play following a score is conducted under procedures which vary with the type of score.The game consists of two 30-minute halves, each of which is divided into two 15-minute quarters. The clock counts down from 15:00 in each quarter. Timing rules change when there are three minutes remaining in a half.
A 2-minute interval occurs after the end of each quarter (15 minutes at halftime, except 30 minutes in Grey Cup), and the two teams then change goals.
Penalty (gridiron football)
Moreover, the game clock will run once the ball is placed. If such a runoff occurs with 10 seconds or less remaining, the half automatically ends. Since the enforcement of the 10-second runoff, eight regular season NFL games ended automatically due to this rule: 2005 Arizona-St. Louis, 2009 Cincinnati-Green Bay, 2011 Chicago-Oakland, 2012 Washington-Philadelphia, 2012 New England-Arizona (which cost New England the chance to attempt a field goal at the end of the half in a game they eventually lost by two points), 2014 St. Louis-Tampa Bay (which cost Tampa Bay a chance to attempt a game-winning field goal), 2015 New England-New York Jets (which cost the Jets an attempt to throw a Hail Mary and force the game to overtime) and 2017 Atlanta-Detroit (which cost the Lions a chance to win the game). A pre-season game in 2006 between Houston and Kansas City had the first half end automatically due to an intentional grounding foul with less than 10 seconds left. A 2013 divisional playoff game between the New Orleans Saints and the Seattle Seahawks also ended on a 10-second runoff after Saints wide receiver Marques Colston threw an illegal forward pass.
Continental Indoor Football League
Playing Time – Four 15-minute quarters with a running clock. Clock only stops for incomplete passes and out of bounds plays during the final minute of the second and fourth quarters. 25-second play clock.
National Football League on television
Sunday afternoon games in the Mountain and Pacific time zones are always scheduled for 2:05 or 2:25 p.m. Mountain Time and 1:05 or 1:25 p.m. Pacific Time. (No 10:00 a.m. PT or 11:00 a.m. MT games are ever scheduled, partly to avoid conflict with religious services in those cities.)
National Football League
NFL regular season matchups are determined according to a scheduling formula. Within a division, all four teams play fourteen out of their sixteen games against common opponents – two games (home and away) are played against the other three teams in the division, while one game is held against all the members of a division from the NFC and a division from the AFC as determined by a rotating cycle (three years for the conference the team is in, and four years in the conference they are not in). The other two games are intraconference games, determined by the standings of the previous year – for example, if a team finishes first in its division, it will play two other first-place teams in its conference, while a team that finishes last would play two other last-place teams in the conference. In total, each team plays sixteen games and has one bye week, where they do not play any games.
Tiebreaker
In the National Football League of professional American football, if both teams are tied at the end of regulation, an overtime period is played under modified "sudden death" rules. Before the 2017 season, this period was 15 minutes in all games. Since 2017, a 15-minute period has been used only in playoff games (in which a winner "must" be decided); overtime in preseason and regular-season games consists of a 10-minute period. If the team that receives the ball first scores a field goal, then the opponent must receive a chance at equalising that score of their own; the first team to score a touchdown or safety wins the game; and once both teams have had possession of the ball in overtime, the first team to score under any legal means, touchdown (offensive or defensive), field goal or safety, wins. If neither team scores before the end of the overtime period, or both teams score one field goal each, the game is considered a draw and ends, and counts as a "half-win" in the standings for purposes of winning percentage for both draft order and playoff positioning. However, in the playoffs, true sudden death rules apply from double overtime onwards.
Official (American football)
Because their regular season spans only 17 weeks, the NFL is one of only two major sports leagues in the United States that only pay their officials on a contract basis as opposed to being full-time salaried employees, the other being Major League Soccer. Advantages to this system include being able to eliminate unqualified officials simply by not offering them a contract the following season, where terminating full-time employees would require them to show cause. Critics argue that full-time officials would be free from the distractions of a second job, but proponents of part-time officials point out that the NFL would lose a number of qualified officials because many of them are owners, presidents, or CEOs of various companies. Proponents also argue that there is only one game per week and the regular season is only four months long, and that having full-time officials does not necessarily guarantee that they will make fewer officiating mistakes. The level of training and review in which NFL officials participate makes additional time redundant. In any event, veteran officials can earn substantial salaries for their work. The NFL Referees Association serves as the union that represents officials in the NFL.
American football rules
Teams change ends of the field at the end of the first quarter and the end of the third quarter, though otherwise the situation on the field regarding possession, downs remaining and distance-to-goal does not change at these occasions (so a team with possession 5 yards from the opponent's endzone at the end of the first quarter would resume play 5 yards from the endzone at the other end of the field, which they would then be attacking) . Separating the first and second halves is "halftime." Both halves, and any overtime, begin with kick-offs — the kicking team is decided by a coin toss (see below).
American football rules
If a game is tied at the end of four quarters, "overtime" is played. In overtime, the coin is tossed to determine which team will possess the ball first. The winner of the coin toss can choose to give the ball or receive the ball. If the first possession results in a field goal, the other team is given possession to match or better the field goal; therefore continuing the game. If the first possession results in a touchdown or safety, the scoring team wins. During the regular season in the NFL, one overtime period is played (with each team receiving two time outs). If both teams are tied after the 10-minute overtime, the game officially ends in a tie. In the playoffs, 15-minute overtime periods continue until a winner is determined. Overtime follows a three-minute intermission after the end of the regulation game. Prior to start of overtime, a coin flip is performed in which the captain of the visiting team calls the toss. The team that wins the coin flip has the option either to receive the kickoff or choose the side of the field they wish to defend. Ties are rare in the NFL; a game between the Minnesota Vikings and Green Bay Packers on September 16, 2018 ended in a 29–all draw. The previous occurrence was one week earlier, on September 9, 2018.
Comparison of American and Canadian football
American football rules allow each team to have three timeouts in each half, and the NFL stops play for a "two-minute warning". However, NCAA football has no two-minute warning, but the clock stops on a first down until the ball is ready for play if the play ended in the field of play. In the CFL, each team has two time-outs a game but cannot use both in the last three minutes of the game, while at lower levels of Canadian football each team has two. In Canadian football there is a three-minute rather than a two-minute warning. Also, at all levels of Canadian football, the clock is stopped after every play during the last three minutes of each half. Once the referee has set the ball the clock will restart if the last play ended with a runner tackled in the field of play.
Association football
A standard adult football match consists of two halves of 45 minutes each. Each half runs continuously, meaning that the clock is not stopped when the ball is out of play. There is usually a 15-minute half-time break between halves. The end of the match is known as full-time. The referee is the official timekeeper for the match, and may make an allowance for time lost through substitutions, injured players requiring attention, or other stoppages. This added time is called "additional time" in FIFA documents, but is most commonly referred to as "stoppage time" or "injury time", while "lost time" can also be used as a synonym. The duration of stoppage time is at the sole discretion of the referee. Stoppage time does not fully compensate for the time in which the ball is out of play, and a 90-minute game typically involves about an hour of "effective playing time". The referee alone signals the end of the match. In matches where a fourth official is appointed, towards the end of the half the referee signals how many minutes of stoppage time they intend to add. The fourth official then informs the players and spectators by holding up a board showing this number. The signalled stoppage time may be further extended by the referee. Added time was introduced because of an incident which happened in 1891 during a match between Stoke and Aston Villa. Trailing 1–0 and with just two minutes remaining, Stoke were awarded a penalty. Villa's goalkeeper kicked the ball out of the ground, and by the time the ball had been recovered, the 90 minutes had elapsed and the game was over. The same law also states that the duration of either half is extended until the penalty kick to be taken or retaken is completed, thus no game shall end with a penalty to be taken.
In league competitions, games may end in a draw. In knockout competitions where a winner is required various methods may be employed to break such a deadlock; some competitions may invoke replays. A game tied at the end of regulation time may go into extra time, which consists of two further 15-minute periods. If the score is still tied after extra time, some competitions allow the use of penalty shootouts (known officially in the Laws of the Game as "kicks from the penalty mark") to determine which team will progress to the next stage of the tournament. Goals scored during extra time periods count towards the final score of the game, but kicks from the penalty mark are only used to decide the team that progresses to the next part of the tournament (with goals scored in a penalty shootout not making up part of the final score).
Mercy rule
In some states (where 8-man and 6-man football is widely used), the rules call for a game to end when one team is ahead by a certain score (like 45 or 50 points) at halftime or any time thereafter. In other states with 6- or 8-man football, continuous clock rules are used, and the rule may be modified; for instance, in Iowa, the rule goes into effect if the 35-point differential is reached at any time after the first quarter.
Mile High Miracle
At 76 minutes and 42 seconds, the game was the 4th-longest in NFL history and was the sixth double overtime game in history, the first since the 2003 divisional round game between the St. Louis Rams and the Carolina Panthers, which coincidentally also featured head coach John Fox.
Gridiron football
At all adult levels of the game, a game is 60 timed minutes in length, split into four 15-minute quarters. (High school football uses 12-minute quarters, and the general rule is that the younger the players, the shorter the quarters typically are.) Because of the halftime, quarter breaks, time-outs, the minute warnings (two minutes before the end of a half in the NFL, three minutes in Canadian football), and frequent stoppages of the game clock (the clock stops, for example, after every incomplete pass and any time a ball goes out of bounds), the actual time it takes for a football game to be completed is typically over three hours.
United Indoor Football
A game consisted of four 15-minute quarters with a halftime intermission 20 minutes in length. The clock typically only stopped for time-outs, penalties, injuries, and official clarifications. Further stoppages occurred for incomplete passes and out of bounds during the final 90 seconds of the second and fourth quarters. A mandatory official's time-out, called a promotional timeout, was assessed after the first and third quarters and is 90 seconds in duration. Another mandatory official's time-out, called a warning period, was assessed with 90 seconds to play at the end of each half. The game could also be stopped for further promotional time-outs but not exceed 90 seconds per league rules.
American football rules
In the NFL, a number of rulings can be reviewed by officials or challenged by coaches. If a coach wants to challenge a play, he must do so before the next play begins, and he does so by throwing a red flag similar to the officials' yellow flags. Coaches are allowed two challenges per game and are granted a third if their first two are successful. The team loses a timeout if they lose the challenge. Therefore, they cannot challenge if they do not have timeouts. Plays within the two-minute-warning and overtime cannot be challenged; any review must be initiated by a replay official off-field. The referee performs the actual review via a video screen on the sideline. The referee will announce the result of instant replay reviews over his wireless microphone.
Backyard Basketball
Each quarter of a game lasts approximately three minutes while each overtime period (if necessary) lasts approximately one minute. The longer characters play without rest, the more tired and prone to mistakes (poor shooting and ball-handling) they will be; as such, substitutions can be made after any completed play or during a time-out. Characters will recover their energy while on the bench (only two players can stay on the bench at a time). Granted, a character's energy will never decrease if the fatigue option is turned off.
National Academic League
In second quarter, five members of the buzzer team work as a team to answer lengthy questions. There is a back row of five reserve players, but this reserve used only at the discretion of the team coach, who can substitute any or all backup players for any or all active players. This quarter lasts ten minutes with 60 seconds (maximum) for each question. The questions are printed on a card, which is carried to the team by a player of the opposite team, the "runner". When the judge says "Drop", each runner drops the card down on the table. The time starts when the judge reads the question aloud. Players are allowed to talk with each other and write down answers, and collaborate. Although communication is a prime skill in second quarter, no other team member may speak after the captain has buzzed in. Each correct answer is worth three points.
Indiana High School Rugby
Unlike senior level clubs, which play two forty-minute halves, youth rugby in the United States is capped below the traditional eighty-minute match. In Indiana, matches are scheduled for two thirty-minute halves, with players not allowed to participate in more than ninety minutes of scheduled match time in a single day. In competitions in which teams compete in multiple matches, the total length of the match is truncated to comport with the ninety-minute daily cap, thus, the matches are contested at two halves each of 22.5 minutes in duration. Matches consist of fifteen players on the field for each team along with eight reserves on the bench (23 total). Matches will end in a draw if level at the end of full-time unless in a championship competition. In a championship competition, if the match is level at full-time, an additional ten-minute sudden death period is played. If the match remains level after sudden death, then the outcome is decided on drop kicks. If multiple matches are to be contested in a single day, the sudden death period is foregone. Coed play at the high school level is not permitted. The coed prohibition was tested in May 2001 by the Mishawaka High School boys squads' attempt to include Nicole Kodba in its playoff lineup. Despite arguments from her coach and a community petition, Kodba was not allowed to compete for the boys team.
List of gridiron football rules
The clock does not run during convert attempts in the last three minutes of a half. If the 15 minutes of a quarter expire while the ball is live, the quarter is extended until the ball becomes dead. If a quarter's time expires while the ball is dead, the quarter is extended for one more scrimmage. A quarter cannot end while a penalty is pending: after the penalty yardage is applied, the quarter is extended one scrimmage. Note that the non-penalized team has the option to "decline" any penalty it considers disadvantageous, so a losing team cannot indefinitely prolong a game by repeatedly committing penalties.
American football rules
Officials also call for media time-outs, which allow time for television and radio advertising. They also stop the clock after a change of possession of the ball from one team to the other. Successful PATs (Point(s) After Touchdown), a field goal try, or a kickoff may also warrant stopping the clock. If an instant replay challenge is called during the game, the referees signal for a media time out. The referee signals these media time-outs by first using the time out signal, then extending both arms in a horizontal position.
Football Night in America
Prior to the Wild Card Saturday doubleheader, a half-hour version of "Football Night in America" is broadcast featuring an in-depth preview of the first game; during the afternoon halftime, a special edition of the "Sunday Night Football" halftime show is also broadcast. After the conclusion of the afternoon game and before the kickoff of the night game, an edition known in 2007 as the "Diet Pepsi Bridge Show" aired.
Mercy rule
The National Collegiate Athletic Association's mercy rule provides, "Any time during the game, the playing time of any remaining period or periods and the intermission between halves may be shortened by mutual agreement of the opposing head coaches and the referee." (NCAA Football Rule 3-2-2-a) NCAA Football Approved Ruling 3-2-2-I cites an example: "At halftime the score is 56–0. The coaches and the referee agree that the third and fourth quarters should be shortened to 12 minutes each. The coaches also request that the second half be played with a 'running clock' i.e., that the game clock not be stopped." The NCAA Football Rules Committee determined, "The remaining quarters may be shortened to 12 minutes each. However, the 'running clock' is not allowed; normal clock rules apply for the entire game."
List of gridiron football rules
As in regular American football, each team usually has four downs per series. In order to achieve a series of downs, backyard football requires the team with the ball to complete two passes or reach a certain point on the field. Few games include enough people to run a chain crew to maintain the 10 yard familiar in most organized leagues. These structures encourages passing plays over running, as does the usual lack of offensive and defensive lines. Play continues until there is a turnover on downs (i.e. the offensive team fails to complete two passes in four downs), an interception occurs, or the team on offense scores a touchdown. Touchdowns are worth 6, 7, or 1 point(s) depending on the rules set out before the game.
American Football Conference
Each AFC team plays the other teams in their respective division twice (home and away) during the regular season, in addition to 10 other games assigned to their schedule by the NFL. Two of these games are assigned on the basis of a particular team's final divisional standing from the previous season. The remaining 8 games are split between the roster of two other NFL divisions. This assignment shifts each year and will follow a standard cycle. Using the 2012 regular season schedule as an example, each team in the AFC West plays against every team in the AFC North and NFC South. In this way, non-divisional competition will be mostly among common opponents – the exception being the two games assigned based on the team's prior-season divisional standing.
2000 Miami Dolphins season
At the beginning of the fourth quarter, Miami led New York 30–7. The Jets then proceeded to quickly close the 23-point deficit throughout the fourth quarter. By 3:55 left in the game, New York tied the game at 30–30, after scoring three touchdowns and a field goal, with a failed two-point conversion. About 22 seconds later, Miami scored a touchdown to re-take the lead. However, New York answered with another touchdown with 42 seconds left in regulation. Neither team scored again and the game went into overtime because of a 37–37 tie. In the fourth quarter, the Dolphins had only 1 first down versus 20 for the Jets, which was more than 15 other NFL teams had in their entire game in week 8. During overtime, Fiedler was intercepted about one minute in by Marcus Coleman, but Coleman fumbled and Miami recovered. However, Fiedler was soon intercepted again by Coleman; this time, the Dolphins were successfully overturned. The Jets then drove the ball to Miami's 23 yard line. With 8:13 left in overtime, John Hall kicked a field goal, ending the game 40–37 in favor of New York. The Dolphins fell to 5–2.
High school football
Thirty-four states have a mercy rule that comes into play during one-sided games after a prescribed scoring margin is surpassed at halftime or any point thereafter. The type of mercy rule varies from state to state, with many using a "continuous clock" after the scoring margin is reached (wherein, except for specific situations, the clock keeps running on plays where the clock would normally stop), while other states end the game once the margin is reached or passed. For example, Texas uses a 45-point mercy rule (to stop the game) only in six-man football; for 11-man football there is no automatic stoppage but the coaches may mutually agree to use a continuous clock.
Super Bowl LI
Mohamed Sanu stated the long length of the halftime show played a part in Atlanta ultimately losing the game. Teams on average are off the field for fifteen minutes during halftime, but Super Bowl halftimes are considerably longer. Unlike the Falcons it appears Bill Belichick actually incorporated the length of the show into the team's practices. Sanu's argument was discounted by the fact that Atlanta marched the ball downfield and scored a touchdown right out of halftime.
National Football League
The National Football League (NFL) is a professional American football league consisting of 32 teams, divided equally between the National Football Conference (NFC) and the American Football Conference (AFC). The NFL is one of the four major professional sports leagues in North America, and the highest professional level of American football in the world. The NFL's 17-week regular season runs from early September to late December, with each team playing 16 games and having one bye week. Following the conclusion of the regular season, six teams from each conference (four division winners and two wild card teams) advance to the playoffs, a single-elimination tournament culminating in the Super Bowl, which is usually held in the first Sunday in February, and is played between the champions of the NFC and AFC.
National Academic League
There are also four quarters or rounds in a game. Each quarter is different from all the others in some way which will be explained below. The buzzer team competes in the first, second, and fourth quarters, but the buzzer team members may be different from quarter to quarter. The presentation team competes in the third quarter, and some may compete in the fourth quarter.
College basketball
As of the most recent 2017–18 season, NCAA men's games are divided into two halves, each 20 minutes long; NBA games are played in four quarters of 12 minutes each; and WNBA and NCAA women's games are played in 10-minute quarters. The NCAA shot clock gives teams of both sexes 30 seconds to shoot, while the shot clock used in both the NBA and WNBA gives teams 24 seconds. Also, NCAA teams are allowed 10 seconds to move the ball past the halfcourt line (with this rule only having been added to the women's college game in the 2013–14 season), while NBA and WNBA rules allow only 8 seconds. However, like the NBA and WNBA (and high school basketball), during the last minute of each period, the game clock keeps time remaining in the period measured in tenths of a second, rather than full seconds.
Timewasting
In American Football, teams leading late in the game will often make low-risk rushing plays to keep the game clock counting down, as the clock stops on an incomplete pass or a run out of bounds. This can also force the trailing team to use up their timeouts. If the opposing team has no timeouts, a leading team needs to make one first down after the two-minute warning. The quarterback will then "take a knee" on three consecutive plays, wasting 40 seconds each time, to allow the clock to run out.
Golden goal
The National Football League introduced sudden death during the regular season in the NFL in 1974 and had always had it in its playoffs. Like the NHL, the NFL's rule comes into use at the end of regulation of any regular season game. Until 2011, it applied for playoff games as well. A new "quarter" is started, with a kickoff. Whichever team scores first—either through a field goal or through a touchdown, or far more rarely a safety—wins the game and the game ends. Since in the preseason and regular season, teams are given a "fifth quarter" of 10 minutes to decide the game. Originally if neither team scored after 15 minutes the game ended in a tie. Since the season, each team gets one possession to score, unless one of them scores a touchdown or safety on its first possession. Sudden death rules apply if both teams have had their initial possession and the game remains tied. If after the OT period it remains tied during that time, the game still ends.
List of gridiron football rules
A standard football game consists of four 15-minute quarters (12-minute quarters in high-school football and often shorter at lower levels, usually one minute per grade [e.g. 9-minute quarters for freshman games]), with a 12-minute half-time intermission (30 minutes in Super Bowl) after the second quarter in the NFL (college halftimes are 20 minutes; in high school the interval is 15 or 20 minutes; 10 minutes for lower grades). The clock stops after certain plays; therefore, a game can last considerably longer (often more than three hours in real time), and if a game is broadcast on television, TV timeouts are taken at certain intervals of the game to broadcast commercials outside of game action. If an NFL game is tied after four quarters, the teams play an additional period, timed like the fourth quarter, lasting up to 10 minutes. There is a coin toss in the NFL just like the beginning of the game. If the receiving team scores a touchdown during the possession, they win. If they kick a field goal, then the other team gets a possession. If they score a touchdown, they win. If they tie the score by kicking a field goal, then the next team that scores wins. If the team with the first possession turns the ball over without scoring any points, then the first team to score, wins. If the defense scores a touchdown through an interception or fumble recovery, or they get a safety, then they win. In a regular-season NFL game, if no one scores in the overtime, the game ends tied. In an NFL playoff game, multiple 15-minute overtime periods are played, as needed, to determine a winner. These periods are timed as if a game had started over. In the extremely rare case a game would go as far as a third OT—which has never happened in the NFL—there would be no "halftime intermission"; play would resume with a kickoff similar to a normal third quarter.
College Football Playoff
The two semifinal games rotate among six major bowl games, referred to as the New Year's Six: the Rose Bowl, Sugar Bowl, Orange Bowl, Cotton Bowl, Fiesta Bowl, and Peach Bowl. In addition to the four teams selected for the playoff, the final CFP rankings are used to help determine the participants for the other four New Year's Six bowls that are not hosting the semifinals that year. The semifinal games, which take place on the same day, are usually scheduled on Friday, Saturday, or Monday close to or on New Years Day, with flexibility allowed to ensure that they are not in conflict with other bowl games traditionally held on New Year's Day. The National Championship game is then played on the first Monday that is six or more days after the semifinals.
Arena football
The clock stops for out-of-bounds plays, incomplete passes, or sacks only in the last minute of each half or overtime (there is only a one-minute warning, as opposed to the two-minute warning in the NFL and the three-minute warning in the CFL) or because of penalties, injuries or timeouts. The clock also stops for any change in possession, until the ball is marked ready for play; for example, aside from in a half's final minute, time continues to run down after a touchdown, but stops after an extra point or two-point conversion attempt. If a quarter ends as a touchdown is scored, an untimed conversion attempt takes place. The play clock is 32 seconds, starting at the end of the previous play. In all arenas, the final minute of the period is measured in tenths of a second.
SEC Championship Game
Matchups that have occurred more than once:
Division standings are based on each team's overall conference record. The SEC Commissioner's Regulations requires each football team play all eight conference games in a season in order to be eligible to compete for a divisional title and play in the SEC Championship Game. Often, two or more teams tie for the best record in their division and each team is recognized as a divisional co-champion. However, tiebreakers are used to determine who will represent the division in the championship game."NOTE: Although all division rivals meet during the season and NCAA overtime is played, the SEC has provisions in case a game ends in a tie, which is possible under NCAA Rule 3-3-3 (c.2) and (d), Suspending the Game, and Commissioner's Regulations (including a tie game after the end of three periods, at the point the game is suspended in the fourth period, or end of regulation, or if one team had played their overtime period but the opponent had not played, when the game reaches the conference curfew of 1:30 a.m. local time), or if the two tied teams did not play an official game because of weather (including a game that ends before the end of three periods), which is possible because numerous conference teams have had games affected by hurricanes but also lightning. As such, SEC rules, written before overtime was implemented in regular season play, still contain the remaining procedures if those circumstances were to happen."Currently the SEC champion plays in the Sugar Bowl unless they have been selected to play in a College Football Playoff semi-final bowl. In the SEC Championship Game era, eleven winners of the game have gone on to win the national title (outright or shared), with thirteen SEC teams winning national titles overall, including seven consecutive titles from the 2006–2012 seasons. There are two occasions when the SEC champion advanced to the BCS or CFP but lost to another SEC team which won the national championship: In 2011 LSU won the SEC Championship Game and advanced to the BCS National Championship Game which they lost 21–0 to fellow SEC member Alabama, and in 2017 Georgia won the SEC Championship Game and advanced to the College Football Playoff, defeating Oklahoma in the semifinal and advancing to the CFP final game, which they lost 26–23 in overtime to SEC member Alabama.
2019 Pro Bowl
The 2019 game featured the same format as the previous five editions. For the sixth straight year, the Pro Bowl differed from standard NFL game rules and format in that there were no kickoffs and every quarter had a two-minute warning. Also, the play clock was only 35 seconds, and the game clock ran after pass incompletions, except with less than two minutes left in either half (or overtime, had it been necessary).
Women's basketball
Most high school games are played with four 8-minute quarters, while NCAA, WNBA, and FIBA games are played in four 10 minute quarters. In 2015-2016 the NCAA changed the rules to 10 minute quarters from 20 minute halves.
Comparison of American football and rugby league
Generally, American football games last much longer than 80-minute rugby league matches. Because the field is reset after each tackle in American football, it is much slower-paced than the more hectic rugby league, in which play stops for only as long as it takes the tackled player to get back to his feet and return the ball to play. Another major difference is that only the player with possession of the ball may be interfered with in rugby league; defending players interfering with any other attacking player (and vice versa) will incur a penalty. Passing in the two sports also differs: while backward passing is common to both sports, in American football players are allowed to throw the ball forward in certain situations whereas in rugby league forward passing is always illegal. rugby league footballers have to kick the ball or run it forward to advance it downfield. To score a try or touchdown in rugby league, the player has to push the ball directly onto the ground once in the try zone, whereas in American football the player has to simply cross the line. American football also requires its players to use a large amount of protective equipment, including helmets, gloves and padding around the body, whereas protective clothing is much more minimal in rugby league, usually amounting to light padding (if any) and soft head gear (hard helmets being illegal). 
The rugby pitch and American football field are both similar in size with a pitch being 100 meters while a football field is 100 yards.
College soccer
While similar in general appearance, NCAA rules diverge significantly from FIFA Laws of the Game. A manager may make limited substitutions, and each player is allowed one re-entry which must occur in the second half of the match unless the substitution was caused by a player injury resulting from a caution or send-off. All matches have an overtime period if the game remains tied after 90 minutes. As opposed to a regular two-half extra time period, golden goal is applied. If neither team scores in the two ten-minute periods, the match ends in a draw (unless it is a playoff match, then it would go to a penalty shootout). College soccer is played with a clock that can be stopped when signaled to by the referee for injuries, the issuing of cards, or when the referee believes a team is wasting time. The clock is also stopped after goals until play is restarted, and the clock generally counts down from 45:00 to 0:00 in each half. In most professional soccer leagues, there is an up-counting clock with the referee adding stoppage time to the end of each 45-minute half.
Scoreboard
In both the United States and Canadian football codes, the minimum details displayed are the time and score of both teams. A typical high school scoreboard will additionally display the down, the yardage of the line of scrimmage, the yards to go until a first down, the team with the possession (usually signified with the outline of a football in lights next to the possessing team's score) and the quarter. Higher levels will also include play clocks and the number of time outs left for each team. American football scoreboards may include a horn to signal the end of a quarter, but they are not used in larger venues. In those cases, the referee or public address announcer denotes the termination of a quarter vocally via the PA system; formerly quarter ends were denoted with the firing of a starting pistol in the era before digital timing.
National Football League on television
If the doubleheader network's games all finish before 7:30 ET, it is supposed to conclude the post-game show within 10 minutes to protect NBC's pre-game show. If any games finish after 7:30, the post-game program can run until 8:00 ET. However, this restriction seems to apply to game footage only; on several occasions Fox has run its post-game offering to 8:00, despite all games ending before 7:30, by airing only panel discussions and interviews in the latter portion of the show. On the other hand, CBS rarely airs any post-game show after its doubleheaders or 4:05 single-games. This is because "60 Minutes" is one of its signature shows, and CBS makes every effort to start it as close to 7:00 or 7:30—its traditional airtime—as possible.

Play clock
In all levels of Canadian football, the offensive team must run a play within 20 seconds of the referee whistling the play in; in amateur American football, teams have 25 seconds from the time the ball is declared ready for play. In the NFL, teams have 40 seconds timed from the end of the previous down. Before 2008, in college football, the play clock was 25 seconds after the ball was set, but the clock was not stopped for the ball to be set unless the previous play resulted in a stoppage of the clock. Now, the same intervals as the NFL are used, with minor differences for the final two minutes of each half. Various professional leagues have used their own standards; the XFL, for instance, used a 35-second play clock to encourage faster play. Arena football uses a 32-second play clock.
Button football
Game duration: two 25-minutes halves
Stance (American football)
In the National Football League (NFL), the average amount of plays per game is over 60 per team. This means that, in one game, a lineman playing the entire time could enter a stance more than 60 times. However, it is not likely to be the same stance every time. Furthermore, it is important to remember that the offensive team must remain still for one second prior to the ball being snapped. This means that once an offensive player has become set in a stance, he must stay in it until the ball is snapped and the play begins. Additional motion can result in a false start penalty. Defensive players, on the other hand, are permitted to shift as much as they want before a play. It is possible for a defensive lineman to line up in one stance and then change to another just before the play begins. He can even shift his body to another place.
Instant replay
American and Canadian football leagues vary in their application and use of instant replay review. In the National Football League, each coach is allowed two opportunities per game to make a "coach's challenge", and get a third challenge if both of the original two challenges were successful. A challenge can only be made on certain reviewable calls on plays that "begin" before the two-minute warning and only when a team has at least one time-out remaining in the half. The Canadian Football League uses similar rules as the NFL, except the game has a three-minute warning near the end of each half instead of two. In NCAA football, each team only has one challenge per game, and gets a second challenge if the first one is successful.
60 Minutes
Starting in the 2012-13 season, in order to accompany a new NFL rule that the second game of an NFL doubleheader start at 4:25 pm, CBS officially changed the start time of "60 Minutes" to 7:30 p.m. Eastern time on Sundays in Eastern and Central Time Zone markets when there is an NFL doubleheader scheduled to air (there are nine doubleheaders during the NFL season – eight during the first 16 weeks of the season, and the final week) to protect against overruns. The start time remains at 7:00 p.m. Eastern time in markets where only a single game is set to air (markets that have only a 1:00 p.m. Eastern time game on single game weeks, and in markets where a home team's NFL game is on Fox at 4:05 p.m., meaning CBS cannot air a doubleheader because of restrictions imposed by the NFL).
List of gridiron football rules
Scoring and game timing are much different in touch football than its more organized counterpart. For the sake of simplicity, touchdowns are usually worth 1 point and no other scoring is counted (there are no extra point attempts). In a much lesser used variation, a touchdown is worth 6 points and if the player who scored the touchdown can progress in the other direction from the end zone in which he had just scored back to the opposite end zone without being touched, it counts as a two-point conversion. The former scoring method does not allow for other scoring types such as safeties. There is usually no game clock and the game ends when one opponent has reached 10 touchdowns (in the former convention) or 100 points (in a standard convention).The NFL adopted many ideas introduced by the AFL, including names on player jerseys and revenue sharing of gate and television receipts. The older league also adopted the practice of using the stadium scoreboard clocks to keep track of the official game time, instead of just having a stopwatch used by the referee. The AFL played a 14-game schedule for its entire existence, starting in 1960. The NFL, which had played a 12-game schedule since 1947, changed to a 14-game schedule in 1961, a year after the American Football League instituted it; it has been 16-game seasons since 1978. The AFL also introduced the two-point conversion to professional football thirty-four years before the NFL instituted it in 1994 (college football had adopted the two-point conversion in the late 1950s). All of these innovations pioneered by the AFL, including its more exciting style of play and colorful uniforms, have essentially made today's pro football more like the "AFL" than like the old-line NFL. The AFL's challenge to the NFL also laid the groundwork for the Super Bowl, which has become the standard for championship contests in the United States.
Comparison of American and Canadian football
In American football, the offensive team must run a play within 25 seconds of the referee whistling the play in – except in the NCAA (college) and the NFL where teams have 40 seconds from the end of the previous play, or 25 seconds following a penalty or timeout. In Canadian football, teams have 20 seconds regardless of the preceding situation.
Halftime show
A halftime show is a traditional element in an American football and Canadian football game. During the interval between the second and third quarters (normally 20 minutes) some form of entertainment is presented on the field. The entertainment frequently consists of performances by marching bands.
NFL preseason
The exhibition season typically begins the first weekend of August with the Hall of Fame Game; though in some years it can be on the second weekend. Previous seasons have seen the American Bowl game held the last weekend of July. The first full schedule of exhibition games is held the following weekend. Most games are held on Thursday, Friday, or Saturday nights, with one nationally televised game each night of the week: NFL Network airs a Thursday game, CBS and Fox a Friday and Saturday night game each, NBC with Sunday night games, and ESPN a Monday night game. Unlike the regular season, CBS's and Fox's national exhibition game opponents are selected regardless of conference. Four full weekends of games are held. The fourth and final full week of exhibition games (fifth weekend overall) usually has teams playing exclusively on Thursday night (plus Friday, if any), with no national games. This allows teams a few extra days to prepare for the first week of the regular season. It also prevents conflict with the start of the regular seasons for high school and college football, allowing those venues to expand their first weekends' games from Thursday through Monday (Labor Day).
List of gridiron football rules
Quarters were shortened to two minutes (default setting) with a faster running timer than real time. For most releases, a first down meant you would have to go 30 yards, instead of ten yards.
American football rules
Each team receives three timeouts per half (if the game goes to overtime, each team receives additional timeouts), making for a total of six timeouts per team in a regulation game. Unused timeouts may not carry over to the second half or overtime. In professional football, a team must have at least one remaining timeout to challenge an official's call.
American football rules
The defunct World Football League, in its first season of 1974, used an overtime system more analogous to the system long used in international soccer. The overtime consisted of one 15-minute period, which was played in its entirety and divided into two halves of 7½ minutes each, with each half starting with a kickoff by one of the teams. The league changed to the NFL's sudden-death format for its final season in 1975.
Running out the clock
In both professional and college football, the offense has 40 seconds (in the Alliance of American Football, 30) from the end of the previous play to run the next play. A team running out the clock will allow the play clock (which records the time remaining until a play must be run) to drain as much as possible before running its next play. In the NFL, this is particularly noteworthy due to the existence of the two-minute warning. If the trailing team has no timeouts remaining and the leading team is in possession of the ball with a first down at the two-minute warning, they can effectively run out the clock and win the game without running another positive play. With two minutes to go (120 seconds), the offense can take three "knees", one each on 1st, 2nd, and 3rd down (using all 40 seconds from the play clock on each), and allow the game clock to expire before having to run a play for fourth down. A similar situation can be had by also achieving a first down inside the two-minute warning. This practice is commonly known as the "Victory Formation", as the offense lines up in a tightly-protective "V" formation to minimize the chances of a fumble or other turnover. (The AAF lets teams run out the clock on three straight victory formations from 90 seconds left in regulation.)
Football Night in America
In the third segment, the studio team moved to a screening room, in which highlights of the daytime games were reviewed. "Football Night in America" is the only pre-game show that the NFL allows to carry long-form highlights (running up to three minutes, twice as long as the usual allowance). Because of Game 2 of the 2006 World Series, and the preference that no NFL game competes against the Major League Baseball championship series, a one-hour edition aired from 7:00 to 8:00 p.m. on October 22. Additionally, as the NFL spurned Christmas Eve contests (a policy that was revoked in 2007), another one-hour show aired on December 24.
Official (American football)
In high school and minor leagues, the line judge is the official timekeeper of the game. In the NFL, college, and other levels of football, the official time is instead kept on the stadium scoreboard clock, and the line judge becomes the backup timekeeper.
Pro Quarterback
The colors of the team's uniforms are almost the same as the uniforms used in the 1992 NFL season, however. Six different surfaces can be used along with quarters ranging from two minutes to a full 15 minutes. The referee call delay of game penalties in the game when the play clock runs out, the only penalty in the game. There is no other penalties in the game, making offsides and roughing the quarterback into workable strategies. Players are notoriously slow in this game; it is possible for six defensive linemen to catch up with the quarterback and sack him before he is ready to make a forward pass. The announcer will call "interception", when a defensive player catches the ball or "fumble", if the ball is loose during a play. A humorous animation is played after an incomplete pass, interception, or fumble during play selection on the scoreboard.
Half-time
While it exists mainly to allow competitors to rest briefly and recover from the play of the first half, half-time also serves a number of other purposes. It also serves as an intermission for spectators, and it often features entertainment, such as cheerleading performances, tifos, performances by school marching bands (particularly in high school and collegiate sports in North America), or concerts featuring popular music acts (particularly in major events, such as the Super Bowl). On games that are broadcast on television and radio, it also provides broadcasters with an opportunity to give a recap of the first half of the game, air highlights of other games in progress, air commercials and other advertisements, provide analysis on the game, or air game-related festivities (such as an aforementioned half-time performance). In the NFL (National Football League), halftime is usually around 12 minutes, although for major events like the Super Bowl it may last much longer to allow for more activities like musical performances.
American Ultimate Disc League
The field area is expanded to yards wide and 80 yards long with 20 yard end zones (the same size as an American football field, but with the end zones taking up twice as much of the field as in American football). Games are timed with four quarters of 12 minutes each, including a 15-minute halftime. If the score is tied, a five-minute overtime period is played. If the score remains tied after overtime, a second overtime is played in which the first team to score wins.
Conversion (gridiron football)
In American football, the game clock does not run during an extra-point attempt, except for some rare circumstances at the high-school level (some state associations allow for the clock to run continuously in the second half if one team is leading the other by a large margin) and for arena football, which runs the clock continuously except during the final minute of each half and overtime. In Canadian football, the clock runs during a conversion attempt except during the last three minutes of each half.
American football rules
If a game goes to overtime, a coin toss is held before the start of overtime, but tosses are not held before the start of subsequent overtime periods. In college, for example, the loser of the toss to start overtime has first choice in the second overtime period. The choices available to the captains in overtime vary among the NFL, college, and various states' high school rules.
Clock management
Each team is given three timeouts per half which they can use to stop the clock from running after a play. In the NFL, teams get two timeouts in a preseason or regular season overtime period, or three in a postseason overtime half.
NFL Sunday Ticket
This channel shows eight games at once, along with the game's score, time left in the game, and the quarter that the game is in under the game's feed. Starting in 2008, it added a high-definition feed, and in 2011, it added larger cells when four or fewer games are being played.
National Academic League
The buzzer team competes in first quarter. First quarter lasts for exactly ten minutes with fifteen seconds (maximum) for each question. (Until recently, the quarter lasted twelve minutes.) Five members sit in the front row and five in reserve. The first question goes to chair one, the captain. If (s)he answers correctly, two points are added to the team's score. The second question will go to chair two. If (s)he also answers correctly, two more points are added to the score and the question goes to chair three. If (s)he also answers correctly, two more points are added, "but the team does not get another question." After three correct answers, the questions go to the opposing team.
National Football League on television
Since 1998, early games have the precise, official start time of 1:01 p.m. ET, which allows for one network commercial and the NFL broadcast copyright teaser animation. However, game times are generally advertised simply as 1:00 p.m. starts. In addition, the league revised the late games to start at 4:05 p.m. ET if it was the only game televised by the network that week and to start at 4:15 p.m. ET if it was part of a doubleheader. The additional 15 minutes for doubleheaders allowed the early games extra time to be shown to completion, and avoid continuing past the late game's scheduled kickoff. For single games, only 5 minutes were added to allow the network time for a short introduction (as three hours had passed since the pre-game show has aired) and one commercial break before kickoff. In those cases there is no need to avoid early-game overlap as there is no early game shown. In addition, it allows those games to end earlier.
Comparison of American football and rugby union
In rugby, the kickoff to begin each half and restarts after scores are taken from the halfway line whereas in American football these can be taken from the 30, 35 or 40 yard line depending on if it is a college, NFL or high-school game. The yard lines of American football are vitally important during game play because a team's advance is measured against them which, in turn, determines possession of the ball. The 22 metre lines in rugby union effectively divide the field into approximate quarters (though not always as rugby pitches vary in size; the total length of the field of play must not exceed 100m but can be shorter than that if space is limited). The 22 metre lines determine the position from which "drop-outs" are taken and also mark the limit where a defending player may kick-the ball directly (without bouncing) into touch without losing the ground gained by the kick.
2015 Lamar Cardinals football team
The game was divided into four ten-minute quarters with a 15-minute half time. Kickoffs, kick returns, and turnovers were live. Field goals and extra points were not live. The White team won 7–3 with all scores in the second quarter.
Quarterback kneel
In Canadian football, which use slightly different rules, kneeling with time left is not necessarily a viable strategy. Unlike in American football, in Canadian football every quarter must end with a play even in situations where the game clock expires after the end of the previous play. However, a quarterback kneel is by far the most common play for winning teams to run with ""zeros on the clock"" at the end of a game, barring exceptional (but not unheard-of) situations where the head-to-head point differential in the opposing teams' season series (a key factor in tiebreakers) remains in doubt.
One-minute warning
At the one-minute mark of any given half or overtime, the referee announces: "One Minute Timing Rule in effect". During the final minute of play, the game clock changes from a continuously running clock (except for scores and time-outs) to a clock that mirrors NCAA rules (stopping on first downs, out of bounds, incompletions, and so on.) Since 2018 teams can do "sandbagging" via the quarterback kneel, a tactic common in the NCAA and NFL to run out the clock with minimum risk. It also rewards defensive play, as a tackle for loss automatically stops the clock. Any player injured during this time and that team uses a timeout.
In the former X-League, after the one-minute warning or in overtime, the "X-Bonus" rule came into play. All scoring during the final minute of play was worth double what it is normally worth, and a special black football was used.
AFC Championship Game
The AFC Championship Game is the annual championship game of the American Football Conference (AFC) and one of the two semi-final playoff games of the National Football League (NFL), the largest professional American football league in the United States. The game is played on the penultimate Sunday in January by the two remaining playoff teams, following the AFC postseason's first two rounds. The AFC champion then advances to face the winner of the National Football Conference (NFC) Championship Game in the Super Bowl.
National Football League on television
The NFL regular season usually begins in September, and ends in December or early January. Each team plays 16 games during a 17-week period. Traditionally, the majority of each week's games are played on Sunday afternoon. The Sunday afternoon games are televised regionally, where the particular game available on local television will depend on where the viewer is located, and begin at either approximately 1 p.m. or 4 p.m. Eastern Time. In addition, there are usually single nationally televised games each on Thursday night, Sunday night, and Monday night. These primetime games are broadcast across the country over one national over-the-air broadcast or cable network, where there are no regional restrictions, nor any other competing NFL contest.
NFL RedZone
As the games enter halftime, the coverage shifts over to games still finishing up the second quarter, even if there are no teams in the red zone. Some noncompetitive games that would otherwise not be looked at may take the attention for a few minutes, in order to fill the broadcast with as much live football coverage as possible. As soon as better games start returning for the third quarter, second half kickoffs typically take a priority.
International rules football
An international rules match lasts for 72 minutes (divided into four quarters of 18 minutes each). Inter-county Gaelic football matches go on for 70 minutes, divided into two halves, and Australian rules matches consist of four 20 minute quarters of game time, although with the addition of stoppage time, most quarters actually last between 25 and 30 minutes.
Big 30 All-Star Football Game
Each team consists of 43 players from a 15 school-district area in each state (15+15 being the "30" indicated in the game's title). New York's team covers mostly Cattaraugus County, portions of Allegany County, and two small districts in southeastern Chautauqua County, while Pennsylvania's team covers a five-county area including Warren, McKean, Cameron, Potter and Elk Counties. This area roughly, though not exactly, corresponds to the coverage area of the Olean Times Herald, the major newspaper serving the region. The players are mostly high school graduates; some go on to play college football but many do not. Unlike most high school football games in New York and Pennsylvania, most games have full fifteen-minute quarters; the standard for most high school games is twelve minutes.
Laws of Australian rules football
The length of a game of Australian Football can vary from league to league, but is generally around 15 to 25 minutes per quarter. In the AFL, each quarter runs for 20 minutes plus time on – which makes up for time occupied in stoppages, such as when the ball goes out of bounds, injuries, goals (or behinds) being kicked, or when the umpire is setting the angle of a free kick on goal. A typical AFL quarter might run from 27 to 33 minutes, but may be even longer if, for instance, injuries cause delays. AFL breaks after the first and third quarters are 6 minutes, with a 20-minute break at halftime. Thus, a match with quarters averaging 30 minutes would last about two and a half hours.
Basketball
Games are played in four quarters of 10 (FIBA) or 12 minutes (NBA). College men's games use two 20-minute halves, college women's games use 10-minute quarters, and most United States high school varsity games use 8 minute quarters, however, this varies from state to state. 15 minutes are allowed for a half-time break under FIBA, NBA, and NCAA rules and 10 minutes in United States high schools. Overtime periods are five minutes in length except for high school, which is four minutes in length. Teams exchange baskets for the second half. The time allowed is actual playing time; the clock is stopped while the play is not active. Therefore, games generally take much longer to complete than the allotted game time, typically about two hours.
Mercy rule
At the middle- or high-school level, 34 states use a mercy rule that may involve a "continuous clock" (the clock continues to operate on most plays when the clock would normally stop, such as an incomplete pass) once a team has a certain lead (for example, 35 points) during the second half. That greatly decreases the amount of time taken for a game to complete, which reduces the leading team's chances to score more and the time that the trailing team must spend in facing an insurmountable deficit. In most states, the clock stops only for scores, timeouts (officials', injury, or charged), or the end of the quarter. Plays that would normally stop the clock, such as penalties, incomplete passes, going out of bounds, or change of possession, would not stop the clock. The rule varies by state; for example, the clock does not stop upon a score in Colorado, Kansas (regular-season games only), or Missouri (fourth quarter only).
Time on
Each quarter has a specific length of playing time, which can vary in different forms of the game, but at senior level is usually 20 minutes. When the umpire stops play for a score, injury, the blood rule, to award a 50-metre penalty or to reset play for a mark or free kick, he raises one hand above his head and blows his whistle; this is called "blowing time off". This tells the timekeeper to stop his clock and stop counting down playing time. When the umpire again raises his hand and blows his whistle, called "blowing time on", or when the ball is bounced or thrown in, the timekeeper starts his clock again.
Comparison of American football and rugby league
American football is played on a rectangular field long by 53 1⁄3 yards (48.8 m) wide. Near each end of the field is a "goal line", which are apart. A scoring area called an end zone extends beyond each goal line. Yard lines cross the field every , two rows of hash marks run parallel to the side lines near the middle of the field. At the back of each of the end zones, there are a set of goalposts. American football goalposts were formerly H-shaped and were located on the goal line, but; in 1967, the NFL adopted the current modern offset-fork design, made from extruded steel pipes. The goalposts currently consist of two vertical posts 18.5 feet (5.6 m) apart (24 feet (7.3 m) in high school football) rising from a horizontal crossbar, which is mounted on a single central support post that raises the crossbar to a height of 10 feet (3.0 m), resulting in a two-tined fork shape. The central vertical post is offset from the crossbar toward the rear, placing it as far as possible from the field of play; it is also usually padded to minimize collision-related injuries. In 1974, in the effort to create a safer, unimpeded field of play in the end zone, calculated to produce more passing touchdowns, the NFL relocated the goalposts from the goal line to the end line.
Time on
Time on was first introduced to the Laws of the Game by the Australian National Football Council for the 1928 season. From 1928 until 1994, quarters lasted 25 minutes playing time, and time on was called only for scores and injuries; the rule of thumb was that there would be roughly one minute of time-on for every goal scored. From 1994, the AFL Commission adopted the shorter 20 minute quarter, and introduced time-on for many other stoppages, including a ball-up or boundary throw-in.
American football rules
NFL Europa, a defunct league run by the NFL, used a 10-minute overtime period, with the constraint that each team must have the opportunity of possession; once both teams have had such an opportunity, the overtime proceeds in a manner similar to the NFL's. Thus, if Team A has the first possession of overtime and scores a touchdown and converts their kick (thus being 7 points ahead of Team B), Team A would then kick off to Team B (In the NFL, the game would have ended with the touchdown, without a conversion being attempted). Team B would have to match or exceed the 7 point difference within this ensuing possession; exceeding it would end the game immediately, while matching the difference would result in a kickoff to Team A. From this point, the overtime is sudden death. The defunct United Football League had also used this rule.
Quarterback
As late as the 1960s, running plays occurred more frequently than passes. NFL quarterback Milt Plum later stated that during his career (1957-1969) passes typically only occurred on third downs and sometimes on first downs. Quarterbacks only increased in importance as rules changed to favor passing and higher scoring and as football gained popularity on television after the 1958 NFL Championship Game, often referred to as "The Greatest Game Ever Played". Early modern offenses evolved around the quarterback as a passing threat, boosted by rules changes in 1978 and 1979 that made it a penalty for defensive backs to interfere with receivers downfield and allowed offensive linemen to pass-block using their arms and open hands; the rules had limited them to blocking with their hands held to their chests. Average passing yards per game rose from 283.3 in 1977 to 408.7 in 1979.
The NFL continues to be a pass-heavy league, in part due to further rule changes that prescribed harsher penalties for hitting the quarterback and for hitting defenseless receivers as they awaited passes. Passing in wide-open offenses has also been an emphasis at the high school and college levels, and professional coaches have devised schemes to fit the talents of new generations of quarterbacks.
American Football League
The NFL adopted some of the innovations introduced by the AFL immediately and a few others in the years following the merger. One was including the names on player jerseys. The older league also adopted the practice of using the stadium scoreboard clocks to keep track of the official game time, instead of just having a stopwatch used by the referee. The AFL played a 14-game schedule for its entire existence, starting in 1960. The NFL, which had played a 12-game schedule since 1947, changed to a 14-game schedule in 1961, a year after the American Football League instituted it. The AFL also introduced the two-point conversion to professional football thirty-four years before the NFL instituted it in 1994 (college football had adopted the two-point conversion in the late 1950s). All of these innovations pioneered by the AFL, including its more exciting style of play and colorful uniforms, have essentially made today's professional football more like the "AFL" than like the old-line NFL. The AFL's challenge to the NFL also laid the groundwork for the Super Bowl, which has become the standard for championship contests in the United States of America.
Arena football
Coaches are given 2 (two) challenges per game, as in the NFL; to do so, they must throw the red flag before the next play. If the play stands as called after the play is reviewed they lose a timeout; however, if the play is reversed they keep their timeouts. If a team wins two straight challenges they are granted a third. All challenges are automatic in the final minute of each half and all overtime periods, as they are on all scoring plays and turnovers.
Street football (American)
As in regular American football, each team usually has four downs per series. In order to achieve a series of downs, backyard football requires the team with the ball to complete two passes or reach a certain point on the field. Few games include enough people, or the proper equipment, to run a chain crew to maintain the 10 yard familiar in most organized leagues. These structures encourages passing plays over running, as does the usual lack of offensive and defensive lines. The use of a center is optional, depending on the rules set forth, and other ways to start the play (e.g. the quarterback picking up the ball directly, or holding the ball out prior to starting play, then pulling it back to begin) are often used in lieu of a snap. Play continues until there is a turnover on downs (i.e. the offensive team fails to complete two passes in four downs), an interception occurs, or the team on offense scores a touchdown. Touchdowns are worth 6, 7, or 1 point(s) depending on the rules set out before the game. In some instances, depending on the width of the field more downs are used or teams are given a certain number of downs to score in as opposed to 4 tries to get a first down. For instance, a team might be given 8 tries to score and advance the ball from where they receive the ball or establish position. Also the length of a first down may differ due to the lack of a pass rush. For instance, a team may have to advance fifteen or twenty yards to get a first down in 4 tries.
Overtime (sports)
High school rules vary depending on the state and conference, but most will have a sudden-death overtime procedure wherein the game ends upon scoring a golden goal, although in some instances the overtime will go until completion with the team in the lead after time expires (i.e., silver goal rules) declared the winner. The overtime period length may vary, but it is commonly 10 minutes long. Depending on the state, if the game is still tied at the end of the first overtime:The NFL introduced overtime for any divisional tiebreak games beginning in 1940, and for championship games beginning in 1946. The first postseason game to be played under these rules was the 1958 NFL Championship Game between the Baltimore Colts and New York Giants (the so-called "Greatest Game Ever Played").
Delay of game
In American football, an offensive team is penalized five yards for delay of game if it fails to put the ball in play by either snap or free kick before the play clock expires. This time limit varies by league, and is often 25 seconds from the time the referee signals the ball ready for play. In the National Football League, it can also be 40 seconds from the end of the previous down, depending on the circumstances at the time. Also, the defensive team can be given the same penalty if, after a play has ended, they fail to quickly yield the ball to officials, prevent a player on the offense from getting up, or kick the ball.
Australian rules football
A game consists of four quarters and a timekeeper officiates their duration. At the professional level, each quarter consists of 20 minutes of play, with the clock being stopped for instances such as scores, the ball going out of bounds or at the umpire's discretion, e.g. for serious injury. Lower grades of competition might employ shorter quarters of play. The umpire signals "time-off" to stop the clock for various reasons, such as the player in possession being tackled into stagnant play. Time resumes when the umpire signals "time-on" or when the ball is brought into play. Stoppages cause quarters to extend approximately 5–10 minutes beyond the 20 minutes of play. 6 minutes of rest is allowed before the second and fourth quarters, and 20 minutes of rest is allowed at "half-time".
Modern history of American football
The CFP system is centered on six major bowl games played on or near New Year's Day, often called the "New Year's Six". Three pairs of games rotate annually as hosts of CFP semifinals. The champions of the so-called Power Five conferences (ACC, Big Ten, Big 12, Pac-12, SEC) all receive guaranteed berths in one of the New Year's Six games, though not necessarily in the CFP semifinals. Notre Dame, a football independent but otherwise an ACC member, has its own arrangement for access to the New Year's Six should it meet specified criteria. A selection committee similar to those used by the NCAA basketball tournaments for men and women releases a weekly ranking concurrently with the AP Poll starting with the Monday after Week 10 of the season. After the completion of the regular season, the committee selects the four teams that will compete in the CFP semifinals and the at-large entries to the New Year's Six games. One of the at-large entries is reserved for the top-ranking champion of the so-called "Group of Five" conferences (American, Conference USA, MAC, Mountain West, Sun Belt). The semifinal winners advance to the College Football Playoff National Championship game. The first season of the new system was not without controversy, however, after TCU and Baylor (each with only one loss) both failed to receive the support of the College Football Playoff selection committee.
RealSports Football
Each game is 15 minutes long and is played on a standard 100-yard football field. There are no kickoffs in the game, and each side is given five players. The team on the offensive side of the ball has a quarterback, a flanker, and three offensive linemen (a center and two guards); the user controls the one with the ball. The team on defense has two defensive linemen, two cornerbacks, and one linebacker, which the user controls.
American football rules
In college, coaches are allowed one challenge per game by first requesting a timeout. Otherwise, a replay official in the press box observes all plays. If he deems a ruling may be in error, he notifies the officials on the field to interrupt the game before the beginning of the next play. The replay official performs the review and relays the decision to the referee, who announces the result. Not every conference employs replay, which is optional.
Copa América Centenario
All times are EDT (). In the quarter-finals, semi-finals, and third place match of the knockout stage, a penalty shoot-out was used to decide the winner if tied after 90 minutes. In the final, extra time and a penalty shoot-out was used to decide the winner if necessary. Should the final enter extra time, a fourth substitute would be allowed as part of FIFA's approval of rule changes based on IFAB's new regulations, however neither teams in the final ended up taking advantage of this rule.
Canadian football
During the last three minutes of a half, the penalty for failure to place the ball in play within the 20-second play clock, known as "time count" (this foul is known as "delay of game" in American football), is dramatically different from during the first 27 minutes. Instead of the penalty being 5 yards with the down repeated, the base penalty (except during convert attempts) becomes loss of down on first or second down, and 10 yards on third down with the down repeated. In addition, as noted previously, the referee can give possession to the defence for repeated deliberate time count violations on third down.
Delay of game
The foul known as "delay of game" in American football is called "time count" in Canada. It is generally identical to the American foul, with two important exceptions. First, Canadian football only allows the offensive team 20 seconds from the referee's signal to put the ball in play, as opposed to the longer periods allowed in the American code. Second, the penalty, which is identical to that in the American code during most of the game, including convert attempts at any time, is dramatically different after the Canadian code's three-minute warning near the end of each half. After the three-minute warning, the base penalty becomes loss of down on first or second down, instead of the regular 5 yards. On third down (the final down that the offensive side has to gain a first down), the penalty becomes 10 yards with the down repeated. The referee also has the right to give possession to the defensive team if he deems repeated time count violations on third down to be deliberate.
Harrow football
A standard Harrow football match consists of two periods (known as halves) of 40 minutes each. There is usually a 15-minute break between halves, known as half time. The end of the match is known as full-time.
1923 Niagara vs. Colgate football game
Coach Dwyer of Niagara wanted to play four quarters of eight minutes in length rather than the standard 15-minute quarters, an agreement reached between the schools at an earlier date. Opposing coach Dick Harlow wanted nothing to do with the rule change and insisted on the standard 15 minutes. In protest, the players of Niagara refused to tackle their opponents. Coach Dwyer of Niagara told his team "I will dismiss from the squad any man who makes a tackle. I refuse to ruin you as a football team by playing 60 minutes against a team like that, even if they score 1,000 points." Colgate scored three touchdowns in the first two minutes before Harlow agreed to the 8 minute quarters and resumed the game.
National Bible Bowl
Time limit:
The Game lasts until time runs out or until all questions prepared for the game have been read- whichever comes first. For double or single elimination games, this is 20 questions and two halves of 10 minutes each. For round robin games, this is 15 questions and 14 minutes. There is no half-time in round robin play. There is a timekeeper for each game to make sure the game does not go over the time limit.
