In American Football, there are 100 yards on the field (120 including the 10 yard endzones), however they don't start in the middle of the field...(except for the coin toss).
Despite these precautions, however, player injuries are very common and, in some cases, have resulted in career-ending surgeries. The standard American football field is 120 yards in length and 160 feet in width. There are hash marks every yard and every ten yards. On each end of the field (the first and last 10 yards) is an end zone with an upright consisting of two vertical yellow poles connecting by one horizontal yellow pole.
