PITTSFORD, N.Y. (AP) Buffalo Bills cornerback Leodis McKelvin is out indefinitely and could miss the start of the season after having a follow-up procedure on his broken right ankle.

Coach Rex Ryan gave that assessment after practice Thursday. It was the most detailed update of McKelvin's status since training camp opened last week.

Ryan described the injury as ''significant,'' and didn't know if the starter would for the season opener on Sept. 13. Ryan added the injury is not expected to prevent McKelvin from playing at some point this season.

McKelvin missed spring practices, and opened camp on the active/non-football Injury list. He has worn a protective boot while watching practice from a golf cart.

McKelvin had surgery after breaking the ankle during a game in November.
