The Kansas City Chiefs are undefeated no more. The Buffalo Bills handed them their first loss of the season on Sunday, 30-21, snapping a 15-game win

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.

And leave it to the Buffalo Bills, of all teams, to settle the issue behind their remarkable quarterback.  Allen bolted from the pocket on a fourth-down play with just over two minutes on the clock and didn’t stop until he delivered a finishing blow with a 26-yard touchdown run that essentially sealed the 30-31 verdict in a thriller at Highmark Stadium.
