 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.
