Allen "up in the air" for Week 10

NFL Network's Ian Rapoport hears that Bills QB Josh Allen's status for Sunday's game vs. the Vikings is "up in the air." Rapoport confirms that Allen is dealing with a sprained UCL in his throwing elbow. "Not considered to be a major, major injury," Rapoport adds. "The belief is it's something that he can play through." Allen is expected to be limited in practice to start the week -- and then monitored each day leading up to Sunday. Rapoport also describes the injury as a "functionality issue," rather than a pain-tolerance thing. "Sometimes, with this injury, it affects the grip of the football," Rapoport explains. We'll continue to keep a close eye on Allen's status. QB Case Keenum is Buffalo's backup.
