Bills: QB Josh Allen (elbow) day-to-day, 'we'll see' if he plays play Sean McDermott: Josh Allen is day-to-day (0:31) Sean McDermott comments on Josh Allen's injury and status for Week 10. (0:31) 12:24 PM ET Alaina GetzenbergESPN ORCHARD PARK, N.Y. -- Buffalo Bills quarterback Josh Allen is day-to-day with a right elbow injury to the ulnar collateral ligament and related nerves, according to coach Sean McDermott, and will not practice Wednesday. His status remains uncertain for Sunday's game against the Minnesota Vikings . "We'll see," McDermott said when asked if Allen would play in the game. "We will see how he does," McDermott said. "We use common sense and, obviously, we factor a lot of things in, a medical report being one of them and our doctor's wisdom and knowledge."

Allen was injured during the last drive of the 20-17 loss to the New York Jets . Jets defensive lineman Bryce Huff got past backup right tackle David Quessenberry , in for injured tackle Spencer Brown , and hit Allen's throwing arm, which resulted in a strip sack recovered by Buffalo. After the hit, Allen was seen holding his right elbow and trying to shake out his arm. Two plays after the hit, Allen threw a pass intended for wide receiver Gabe Davis 69.3 yards in the air -- the longest pass attempt over the past six seasons, per NFL NextGen stats. It fell incomplete and ended the game. Allen dealt with an injury to the UCL in his right elbow during his rookie season and missed four games. He has not missed a game since. "There's some slight pain," Allen said after the game, "but we'll get through it." Before the injury, Allen was going through a rough stretch. In the past six quarters stretching to halftime of the win over the Green Bay Packers in Week 8, he has thrown zero touchdown passes to four interceptions and completed 47.9% of his passes. It's difficult to overstate the role that Allen plays on the offense. He has accounted for 23 of the Bills' 25 offensive touchdowns, either with his legs or his arm. If Allen is unable to play, backup Case Keenum , who the Bills acquired in a trade with the Cleveland Browns over the offseason, would step in and face his former team. Keenum has played in two games this season when both were well out of reach. He would face one of his former teams in the Vikings, alongside wide receiver Stefon Diggs , whom he connected with on the Minneapolis Miracle play in the 2017 divisional round of the playoffs. "We believe in Case Keenum," McDermott said. "He's here for a reason." The Bills are dealing with other injuries as pass rusher Greg Rousseau is week-to-week with a high ankle sprain and right tackle Spencer Brown (ankle), linebacker Matt Milano (oblique) and safety Jordan Poyer (elbow) are all coming off injuries that forced them to miss the game against the Jets.
