The Kansas City Chiefs are in their second successive AFC title game.
They got there with a stunning comeback from a 24-0 hole.
Patrick Mahomes threw for four touchdowns in the second quarter in the 51-31 victory.
Kansas City will host Tennessee for the AFC championship and a trip to the Super Bowl. The Chiefs have not been there since winning the 1971 game. The Titans lost their only Super Bowl appearance in 2000.
The NFC title game will have San Francisco hosting Green Bay in what has been a classic playoff rivalry.
