The AFC Championship Game is the annual championship game of the American Football Conference (AFC) and one of the two semifinal playoff games of the National Football League (NFL), the largest professional American football league in the world. 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.

Super Bowl XL was an American football game between the National Football Conference (NFC) champion Seattle Seahawks and the American Football Conference (AFC) champion Pittsburgh Steelers to decide the National Football League (NFL) champion for the 2005 season. The Steelers defeated the Seahawks by the score of 21–10. The game was played on February 5, 2006, at Ford Field in Detroit, Michigan. It is the most recent Super Bowl broadcast on ABC who lost the rights to broadcast Super Bowl games in the next NFL TV contract and the first where all aspects of the game itself were aired in HD. This was the last of 10 straight Super Bowls to feature a team seeking its first win.
