“Horrendous second half,” Allen stated after the match. “I’ve got to be better.”

The win pushed the Vikings’ record to 8-1, giving them a comfortable lead in the N.F.C. North. Seven of their wins this season have been by 8 or fewer points, with none more improbable than Sunday’s victory in blustery and cold conditions.

The Bills have now lost two consecutive games and are currently tied for second in the A.F.C. with the Jets at 6-3 East, perhaps the league’s most competitive division. Kansas City (7-2) is currently the leading contender for the A.F.C.’s best record. and a bye in the playoffs.

The Bills’ past two losses showed how much the team relies on Allen. He arrived in Buffalo as a first-round draft selection in 2018. This sparked a revival and the fifth-year quarterback is now on pace for surpassing 4,000 passing yards for his third consecutive season. He is also the Bills’ leading runner with 476 yards and four rushing touchdowns.

The Bills become vulnerable when Allen attempts to do too many things. Allen was 29 for 43 passing, 330 yards, and one touchdown on Sunday. He also ran for 84 yards. His two interceptions provided the Vikings with the chance to win.

The Bills are in a good place to make it to the postseason, as they have been for a while. And the Bills their fans can exhale now that Allen’s elbow appears strong enough, even after he seemed to injure it further while trying to make a tackle after he threw his first interception on the day. All week, Bills Coach Sean McDermott was coy about Allen’s status. He said Allen’s injury was “day to day” and “hour to hour.” Allen did not practice Wednesday and Thursday. However, he appeared at practice on Friday. He then ran off to avoid scrutiny.

The Bills maintained their winning streak on Saturday Matt Barkley, their third-string quarterbackMcDermott was certain that Allen was healthy enough to participate in the practice squad.

After a slow start Allen led Bills to a commanding 24-10 advantage at halftime. He completed short passes to the sidelines, and scrambled for the first downs. With 1:51 remaining in the third quarter, the Bills extended their lead to 17 points with a field goal.
