Highlights: Buffalo Bills rally for a 24-20 victory over the Kansas City Chiefs

Yeah, sure, it’s only Week 6 of the NFL season, but Sunday’s Chiefs-Bills game at Arrowhead Stadium is huge.

The Chiefs and Buffalo both have 4-1 records, the only one-loss teams in the AFC. The Bills are currently the top seed in the AFC field, with much of the season still to be played.

Just behind Buffalo is Kansas City.

Follow along as we update the highlights from the game, the first between these two rivals since January’s AFC Divisional game, which the Chiefs won 42-36 in overtime.

Final: Bills 24, Chiefs 20

The Chiefs’ Harrison Butker kicked a 44-yard field goal with 9:49 to play in the game, and gave KC a 20-17 lead.

Both teams had a possession but punted, and the Bills put together what proved to be the game-winning drive. Buffalo moved 76 yards in 12 plays and scored the winning points on quarterback Josh Allen’s 14-yard touchdown pass to Dawson Knox with 1:04 to play.

Sixty-four seconds is more than enough time for the Chiefs in most games, but not Sunday. Patrick Mahomes threw an interception that sealed Buffalo’s victory.

Chiefs 17, Bills 17

The Chiefs got the ball to start the second half, but their drive stalled and Harrison Butker tried a 51-yard field goal but it was no good.

Buffalo needed six plays to move 59 yards and ended it with quarterback Josh Allen throwing a 17-yard touchdown pass to Stefon Diggs. That gave the Bills a 17-10 lead.

Back came the Chiefs, who went 83 yards in just seven plays. The biggest gain came on a 43-yard pass from Patrick Mahomes to JuJu Smith-Schuster. Mahomes capped the drive with a 3-yard throw to Mecole Hardman as the Chiefs tied the game at 17-17 with 2:44 left it the quarter.

That was the score heading to the fourth quarter.

Chiefs 10, Bills 10

Buffalo faced a third-and-13 play from its own 1-yard line with 1:18 to play in the first half and appeared to be on the ropes.

Instead, Josh Allen threw an 18-yard pass to Gabe Davis for a first down. Four plays later, Allen connected with Davis again, this time for a 34-yard touchdown that gave the Bills a 10-7 lead with 16 seconds left in the first half.

Buffalo squibbed the kickoff and the Chiefs took over at their 28-yard line with 12 seconds left in the quarter. A 19-yard catch and run by Jerick McKinnon was followed by a 9-yard pass from Patrick Mahomes to Travis Kelce.

With 1 second left in the half, Harrison Butker made a Chiefs record 62-yard field goal. That allowed the Chiefs to tie the game at the half.

JuJu TD No. 1

After a scoreless first quarter, the Bills’ Tyler Bass kicked a 39-yard field goal for the game’s first points.

The Chiefs then moved the ball 79 yards in just six plays and found the end zone. Wide receiver JuJu Smith-Schuster caught a third-down pass from Patrick Mahomes and eluded a trio of Bills defensive players for a 42-yard touchdown on the catch-and-run.

Harrison Butker’s extra point gave the Chiefs a 7-3 lead.

Lots of turnovers

The Bills took the opening drive of the game 60 yards but lost a fumble when quarterback Josh Allen’s backward throw to James Cook hit the turf and the Chiefs recovered at their 11-yard line.

The Chiefs moved the ball 80 yards, but Patrick Mahomes’ pass for Marquez Valdes-Scantling was intercepted in the end zone by Buffalo’s Kaiir Elam.

To sum it up: Two drives to the red zone ended with turnovers. The first quarter end scoreless.

Game referee

The referee for Sunday’s Chiefs-Bills game at Arrowhead Stadium will be Brad Allen, according to Sharp Football Analysis.

Allen is in his ninth season in the NFL, all as a referee. He worked a pair of Chiefs games in the 2021 season. The first was in Nashville when the Titans rolled to a 27-3 win in October. The other was a 48-9 Chiefs victory over the Raiders at Arrowhead Stadium.

Butker officially back

Chiefs placekicker Harrison Butker will handle kicking duties for the first time since the season opener — when he was hurt at Arizona.
