An MRI revealed that Buffalo Bills quarterback Thad Lewis has a mild foot sprain and he is day-to-day, NBC Sports' Pro Football Talk reported Monday.
Lewis, promoted from the practice squad last week to start against the Cincinnati Bengals, threw two touchdown passes and ran for another in the Bills' overtime loss. Lewis was injured late in the game and he was replaced by Jeff Tuel.
If Lewis is unable to play Sunday against the Miami Dolphins, Tuel would likely get the start. The Bills will be without first-round draft pick E.J. Manuel for a few more weeks as he recovers from a knee injury.
The Bills are scheduled to bring in Matt Flynn for a workout. He was recently let go by the Oakland Raiders. They also recently signed Dennis Dixon to the practice squad.
