Josh Allen accounted for two touchdowns and Tyler Bass kicked the tiebreaking 39-yard field goal to help the Buffalo Bills post a 20-17 victory over the host Kansas City Chiefs on Sunday.
Bass’ boot went through the uprights with 1:54 remaining as the Bills (7-6) won for just the third time in their past seven contests. James Cook had a receiving touchdown and 141 scrimmage yards (83 receiving, 58 rushing) for Buffalo.
Patrick Mahomes completed 25 of 43 passes for 271 yards, one touchdown and one interception as the Chiefs (8-5) lost for the fourth time in six games. Travis Kelce had 83 yards on six receptions, Rashee Rice had seven catches and 72 yards and a score and Jerick McKinnon rushed for a touchdown.
High-powered Kansas City has scored 21 points or fewer in five of its last six games.
The contest was Buffalo’s fifth visit to Kansas City in 34-plus months. The Bills won all three regular-season games but lost both playoff appearances during the span.
Allen completed 23 of 42 passes for 233 yards with an interception.
The Chiefs appeared to go ahead on a 49-yard passing touchdown with 1:12 left when Mahomes hit Kelce for 24 yards and the star tight end passed the ball laterally to Kadarius Toney, who ran the final 25 yards.
But the score was nullified because Toney lined up in the neutral zone.
After Kansas City turned the ball over on downs with 55 seconds left, Mahomes was vehemently angry on the sideline, slammed his helmet on the ground and was yelling non-stop.
Buffalo led 17-7 after a 10-play, 62-yard drive to open the second half netted a 31-yard field goal by Bass.
Kansas City answered with a nine-play, 75-yard excursion that resulted in Mahomes’ 4-yard scoring toss to Rice with 3:30 left in the period.
The Chiefs knotted the score at 17 when Harrison Butker booted a 27-yard goal with 11:31 left in the fourth quarter.
Allen passed for one touchdown and rushed for another as the Bills held a 14-7 halftime lead.
Allen connected with Cook on a 25-yard scoring pass with 3:43 left in the opening quarter. Buffalo made it 14-0 on Allen’s 6-yard run with 11:50 left in the first half.
The Chiefs finally got on the board when McKinnon scored on a 7-yard run with 1:19 left in the half.
