Bills CB Corey Graham able to practice Wednesday

Bills cornerback Corey Graham (concussion) will be a limited participant in Wednesday's practice, Chris Brown of the Bills' official site reports.

Graham left the victory over the Colts early and will now try to pass the league's concussion protocol. His initial prognosis is a good sign for the Bills secondary, which could use all the help they can get with Tom Brady and the rest of New England's dynamic offense coming to town Sunday.
