In an absolutely electric scene at Highmark Stadium, the Buffalo Bills handed the Chiefs their first loss of the season. And while Kansas City showed signs of rallying in the fourth quarter, it was Allen who closed the door with his touchdown run to stretch the game to two possessions.

After Mahomes threw another pick to seal the Chiefs' fate, the two superstar quarterbacks met at midfield for a postgame exchange . Mahomes had a five-word message to Allen that seemed to promise the two will see each other in the playoffs: "We'll do it again, baby."

The Chiefs ran out of the late-game heroics that made them appear unbeatable. Josh Allen and the Bills ended the two-time Super Bowl champions’ bid for an undefeated season with a 30-21 win on Sunday.
