Report: Allen being evaluated for UCL injury

Buffalo Bills quarterback Josh Allen is being evaluated for an injury to the ulnar collateral ligament and related nerves in his elbow, a source told ESPN's Chris Mortensen.

Allen appeared to be in discomfort after a hit to his throwing arm on the final drive of the Bills' 20-17 loss to the New York Jets on Sunday. He told reporters postgame that he was experiencing elbow pain, though he wasn't overly concerned about it.

Head coach Sean McDermott said Monday that the team is still evaluating Allen's injury but should have more information in the next 24 hours, according to ESPN's Alaina Getzenberg.

If Allen is unable to play in the Week 10 matchup against the Minnesota Vikings, veteran Case Keenum would be set to start at quarterback.

The 26-year-old Allen has led the Bills to a 6-2 record this season. He's thrown for 19 touchdowns to eight interceptions while averaging a career-high 300.4 yards per game.
