Bills safety Aaron Williams cleared from concussion protocol (The Associated Press)

Bills safety Aaron Williams was too excited to return to practice for the first time in nearly a month to worry about the potential long-term effects his latest head injury might have on his career. ”Honestly, it probably does have an effect on the future,” Williams said at his locker Tuesday. Williams was cleared to practice, and coach Rex Ryan said the starter is ”ready to go” for Buffalo’s season opener at Baltimore on Sunday.
