Bills head coach Sean McDermott said "we'll see," when asked Wednesday if Allen could play Sunday against the Minnesota Vikings.
He's expected to be limited this week with a sprained right elbow.
The goal for Allen is to "manage" the injury without missing a game, NFL Network reported, but McDermott wouldn't confirm those details or disclose the nature of the injury. He wouldn't say if Allen has attempted to throw since he reportedly hurt the ulnar collateral ligament in his elbow in Week 9.
"I'm not going to get into the medical report," McDermott said.
Allen had a sprained UCL in his right elbow in 2018.
