It's sibling rivalry week. The Buffalo Bills host the Kansas City Chiefs in another edition of this continued rivalry, headlining the late window of Week 9 with a nationally televised contest.

The Buffalo Bills notched their fifth straight regular-season victory over the Kansas City Chiefs on Sunday night as Josh Allen outdueled Patrick Mahomes and the defense stepped up.

Allen was masterful, completing 23 of his 26 throws for 273 yards passing and a touchdown while also adding 19 yards on the ground and two goal line rushing touchdowns.
