ORCHARD PARK - Josh Allen remains day to day, but today (Wednesday) could be a big one in terms of his recovery.

Allen will be limited in practice on Wednesday as he tests his injured elbow. He has been throwing since before the weekend. He sprained the elbow in the third quarter of the Bills Week 6 loss at Houston and has been out of action since. That was the first of four straight losses for Buffalo.

Bills head coach Sean McDermott has said if Allen can't play, his choice for a starting quarterback would be veteran Derek Anderson. Anderson remains in concussion protocol and will not practice Wedensday.

McDermott says if both can't play, Nate Peterman would start.

Regardless of who plays at quarterback, the Bills offense desperately needs more production from the running game and top back LeSean McCoy.

McCoy had just ten yards on as many carries in Sunday's loss to Chicago. He has just 267-yards rushing for the season on 85-carries.

McCoy has not spoken to the media since the October 29th Monday night loss to the New England Patriots. The trade deadline passed the following day and McCoy was not dealt.

McDermott says McCoy remains in a "good frame of mind" and will be good to go Sunday. When asked if McCoy had asked for a trade, McDermott would not comment saying those conversations remain private.
