Bills quarterback Josh Allen was knocked out of the team's AFC East matchup against the Patriots after taking a devastating hit in the fourth quarter.
The injury occurred on a seven-yard scramble from Allen with the Bills trailing 16–10. As Allen was being tackled by safety Duron Harmon, Jonathan Jones launched into Allen's head with his helmet. Jones was flagged for unnecessary roughness but remained in the game.
Allen stayed on the ground briefly before walking off the field under his own power. The second-year quarterback jogged into the locker room for further evaluation.
Allen was replaced by Matt Barkley, who completed a 17-yard pass to John Brown on the ensuing play before failing to convert a fourth-and-goal later in the drive.
