Chiefs defeat Bills in overtime in wild divisional round to secure spot in AFC title game

In a never-say-die showdown between two of the NFL's top teams, and two of its bright young quarterbacks, the Bills and Chiefs played a classic Sunday night decided by one of them calling tails and the other making him pay for it.

Josh Allen's decision on the overtime coin toss was his only mistake for Buffalo all night.

Patrick Mahomes promptly followed it by marching Kansas City downfield against the NFL's top-ranked but exhausted defense, then finding Travis Kelce in the corner of the end zone from 8 yards, giving the Chiefs a memorable 42-36 victory.
