The Bills did not get the reprieve from Chiefs quarterback Patrick Mahomes they had hoped for in Sunday's 2021 AFC championship game.

Mahomes was knocked out of the divisional round the previous weekend by a hit to his head area, but he passed though NFL concussion protocol and was brilliant in Kansas City's 38-24 win over Buffalo on Sunday night. He completed 29 of 38 passes for 325 yards and three touchdowns. He didn't turn the ball over.

After Buffalo took a 9-0 lead into the second quarter, Mahomes and the Chiefs settled into an overwhelming performance. Wide receiver Tyreek Hill caught nine passes for 172 yards, and tight end Travis Kelce caught 13 passes for 118 yards and two scores.

The Bills were unable to match the perfection of the Chiefs, punting three times, settling for four field goals and taking four sacks. Josh Allen, who was up-and-down in his first conference title bout, threw an interception early in the fourth quarter that essentially sealed the result.

Kansas City will face the Buccaneers in Tampa in Super Bowl 55 on Feb. 7.
