Flynn, 28, was brought in by the Bills after an injury to quarterback Thaddeus Lewis as "due diligence," according to NFL Network's Ian Rapoport, but a strong workout reportedly sold the team on the former Raiders quarterback. With Lewis listed as "day to day" with a foot sprain, Flynn will compete with Jeff Tuel to be the team's Plan B in the event that Lewis cannot play against the Miami Dolphins in Week 7.
The injury for Lewis is just the latest of a series of injuries at the quarterback position for the Bills, beginning with a preseason concussion for Kevin Kolb. After a knee injury for rookie E.J. Manuel forced Lewis into the lineup, the Bills are again scrambling to find an alternative due to injury.
Flynn has completed 109-of-175 passes in his career for 1,329 yards, 10 touchdowns and six interceptions. In his only start in 2013 with the Raiders, he completed 21-of-32 passes for 227 yards with a touchdown and an interception.
