In a commanding performance, the Kansas City Chiefs defeated the Buffalo Bills 31-7 in Week 12 of the 2026 season. With playoff implications on the line, the Chiefs showcased their dominance on both sides of the ball, securing a crucial victory that solidifies their position in the postseason race. Chiefs quarterback Patrick Mahomes was the standout performer, throwing for 248 yards and three touchdowns, leading his offense with precision and poise. Running back Kenneth Walker added 91 rushing yards to keep the Bills' defense on their toes, while wide receiver Xavier Worthy emerged as a key target, racking up 103 receiving yards. The potent combination of Mahomes' passing and Walker's ground game proved too much for Buffalo to handle. On defense, the Chiefs made pivotal plays that shifted momentum in their favor. Defensive lineman Peter Woods recorded a sack, while safety Eric Berry secured an interception, both contributing to a stifling defensive effort. The game's turning point came in the second quarter when Berry's interception halted a Buffalo drive, allowing Kansas City to extend their lead and ultimately control the game.
