The league added a third game in prime time in 2006, which aired on the NFL Network, then moved to NBC in 2012. The third game has no set site or team, providing an opportunity for all teams in the league to host a Thanksgiving game in the future. For college football teams that participate in the highest level (all teams in the Football Bowl Subdivision, as well as three teams in the historically black Southwestern Athletic Conference of the Championship Subdivision), the regular season ends on Thanksgiving weekend, and a team's final game is often against a regional or historic rival, such as the Iron Bowl between Alabama and Auburn, the Civil War between Oregon and Oregon State, the Apple Cup between Washington and Washington State, and Michigan and Ohio State playing in their rivalry game. Most of these college games are played on the Friday or Saturday after Thanksgiving, but usually one or two college games are played on Thanksgiving itself. The lower divisions of the game, including all of Divisions II and III, the NAIA, club football and the rest of the Championship Subdivision (except the Ivy League, whose season ends before Thanksgiving,) are in the midst of playoff tournaments over Thanksgiving weekend. Some high school football games (which include some state championship games), and informal "Turkey Bowl" contests played by amateur groups and organizations, are frequently held on Thanksgiving weekend. Games of football preceding or following the meal in the backyard or a nearby field are also common during many family gatherings. Amateur games typically follow less organized backyard-rules, two-hand touch or flag football styles. College basketball holds several elimination tournaments on over Thanksgiving weekend, before the conference season. These include the Anaheim-based Wooden Legacy, the Orlando-based AdvoCare Invitational, and the Bahamas-based Battle 4 Atlantis, all of which are televised on ESPN2 and ESPNU in marathon format. The NCAA owned-and-operated NIT Season Tip-Off has also since moved to Thanksgiving week. This is a relatively new phenomenon, dating only to 2006. The National Basketball Association also briefly played on Thanksgiving, albeit in the evening, with a doubleheader airing Thanksgiving night on TNT, a practice that ran from 2009 to 2011; the Atlanta Hawks hosted the early game each year, while the Los Angeles Clippers hosted the late game in both 2010 and 2011 (both of the 2011 NBA Thanksgiving games were canceled due to a labor dispute). The NBA has not scheduled any Thanksgiving games since then, mainly due to the move of the NFL's primetime Thanksgiving game to NBC. Though golf and auto racing are in their off-seasons on Thanksgiving, there are events in those sports that take place on Thanksgiving weekend.
