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.

It was subtle, but Patrick Mahomes had a warning for Josh Allen and the Bills after the Chiefs first loss of the season.

Josh Allen led the Buffalo Bills to a massive 30–21 win over the Kansas City Chiefs on Sunday. The quarterback sealed the win for his team after he ran for 26 yards to score a touchdown on a fourth down in the fourth quarter.
