Not since reaching Super Bowl XXVII had the Bills featured in the AFC title decider, but second-seeded Buffalo ended that 27-year drought after downing the Ravens on Saturday.
The Bills used a 14-0 third quarter to progress in the NFL playoffs as the Ravens – seeded fifth – were held scoreless in the second half in windy Buffalo.
Bills quarterback Josh Allen finished 23-of-37 passing for 206 yards, a touchdown and no interceptions, while he was sacked twice.
Ravens star Lamar Jackson was 14 of 24 for 162 yards, no touchdowns and an interception before he was ruled out with a concussion against the Bills.
The Ravens were made to pay for their inefficient kicking in the opening quarter, which saw Justin Tucker miss two field goals.
Tucker was 11-of-11 on field-goal attempts inside 50 yards in his postseason career, but he was 0-2 on such field goals against Buffalo.
Buffalo's Tyler Bass also missed a field goal, but he managed to convert a 28-yard attempt to give the Bills a 3-0 lead at the end of the opening quarter.
Tucker made no mistake from 34 yards to level the scores at half-time before the Bills took control in the third quarter.
Allen threw a three-yard pass to star team-mate Stefon Diggs with less than 10 minutes to play and Taron Johnson all but ended Baltimore's hopes with a dazzling 101-yard interception return during the closing stages of the period.
Reigning MVP Jackson was ruled out of the fourth quarter due to a concussion after taking a hit from Bills defensive end Trent Murphy on the final play of the third period.
Turning point – Bills pull away in third
The Bills and Ravens could not be separated until the game was blown open in the third quarter.
Allen and Diggs combined for the showdown's first TD before Johnson's electric run essentially sealed Baltimore's fate in front of 6,700 fans amid the coronavirus pandemic.
Johnson matches record
Buffalo's Johnson tied the record for longest intercepted return touchdown in a playoff game, according to NFL Research. Green Bay Packers defensive end George Teague also returned an interception 101 yards for a TD against the Detroit Lions in 1993.
Per Stats Perform, the Bills-Ravens game became the first postseason game where there were three missed field goals in the first half since the 1992 AFC Championship Game between the Bills and Denver Broncos.
The Ravens, meanwhile, will have a busy offseason following back-to-back exits in the Divisional Round.
