Josh Allen ran for a 26-yard touchdown on fourth down with 2:17 left, sealing the Buffalo Bills’ 30-21 win over the Kansas City Chiefs and handing the two-time defending Super Bowl champions their first loss of the season. James Cook rushed for two touchdowns and Allen threw a 12-yard TD pass to Curtis Samuel for Buffalo. The Bills moved to 9-2 and closed the gap on the 9-1 Chiefs in the race for the AFC’s top seed.
