Quarterback Josh Allen’s 26-yard touchdown run with 2:17 remaining clinched the Buffalo Bills’ 30-21 victory over the Chiefs on Sunday, ending Kansas City’s winning streak at 15 games. The Chiefs, who’d been the last undefeated team of the 2024 NFL season, fell to 9-1..

KC’s defense had some good moments but also struggled, for the most part, slowing Buffalo’s pass offense behind Allen. Chiefs cornerback Chamarri Conner had the top highlight, intercepting Allen on fourth-and-3 in the second quarter and returning it 29 yards to set up a Gray 2-yard touchdown.

The Kansas City Chiefs, defending Super Bowl champions, suffered their first loss of the NFL season on Sunday, falling 30-21 at Buffalo after winning their first nine games.While the Bills have beaten Kansas City in each of the past four NFL seasons, the Chiefs have eliminated the Bills from the playoffs in three of the past four seasons.
