Who is in the AFC championship game this year?

For the fourth time in five years, the Kansas City Chiefs and Buffalo Bills will meet in the postseason.
This weekend's AFC championship game will also be the second time in that span that the two AFC titans will play in the title game. It's also the fourth occasion in which the Bills and Chiefs will play a game with a spot in the Super Bowl on the line, dating back to Kansas City's 1966 AFL championship victory that sent the team to Super Bowl 1.
Sunday evening's game will be the seventh postseason meeting and 57th in total between Kansas City in Buffalo. The Chiefs have won each of the last three, dating back to their last meeting in the AFC championship game four years ago.
