After ten years of absence in the play-offs, the Denver Broncos saw their return spoiled by the Buffalo Bills, still one of the best teams in the American conference for several years. Buffalo largely won (31-7) thanks to quarterback Josh Allen (272 yards, two touchdowns) and runner James Cook (120 yards, one TD). In the next round, the Bills will challenge the Baltimore Ravens, qualified on Saturday, while the Kansas City Chiefs, defending champions, will enter these play-offs, facing the Houston Texans, also victorious on Saturday.
