ESPN.com's Adam Schefter and Mike Rodak reported Sunday that Matt Flynn is in Buffalo to work out for the Bills, who are waiting for Manuel -- their first-round draft pick -- to return from a knee injury. The Flynn tryout ostensibly has nothing to do with the sprained foot Lewis suffered in Sunday's overtime loss to the Cincinnati Bengals. Source: NFL.com SteveRobWhatever's Take: Thaddeus Lewis sprained his foot against the Bengals. Early word is the x-rays were negative. Looks like the Bills aren't comfortable with Jeff Tuel manning the ship. While I can't blame them, I don't see how Matt Flynn would be much of an improvement.
