FILE - This Oct. 14, 2012 file photo shows Buffalo Bills' Mario Williams during a timeout against the Arizona Cardinals in an NFL football game in Glendale, Ariz. A person familiar with Williams says the Bills defensive end is visiting a specialist to determine whether to have surgery to repair a nagging left wrist injury. The person spoke on the condition of anonymity on Wednesday, Oct. 24, 2012, because the team had not released that information. (AP Photo/Paul Connors, File)
