The game is played on the last 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 NFC Championship Game in the Super Bowl.

The National Football League (NFL) is a professional American football league that consists of 32 teams, divided equally between the American Football Conference (AFC) and the National Football Conference (NFC). The NFL is one of the major professional sports leagues in the United States and Canada and the highest professional level of American football in the world. Each NFL season begins annually with a three-week preseason in August, followed by the 18-week regular season which runs from early September to early January, with each team playing 17 games and having one bye week. Following the conclusion of the regular season, seven teams from each conference advance to the playoffs, a single-elimination tournament that culminates in the Super Bowl, which is contested in February and is played between the winners of the AFC and NFC championship games.
