The rivalry between the Buffalo Bills and Kansas City Chiefs has become a full-blown saga, with another chapter due in Sunday's AFC divisional round matchup at Highmark Stadium (6:30 p.m. ET, CBS).

It was Jan. 23, 2022 when Patrick Mahomes led the Chiefs to a 42-36 overtime win over Josh Allen and the Bills at Arrowhead Stadium, leading an improbable game-tying drive that started with 13 seconds remaining in the fourth quarter.
