ORCHARD PARK, N.Y. (AP) Buffalo Bills offensive tackle Seantrel Henderson has been limited to working out on his own while continuing to recover from two operations on parts of his intestines to reduce the effects of Crohn's disease.

Coach Rex Ryan was pleased to see Henderson back at the team's facility, and said the player is following a workout plan devised by the Bills training staff. On Wednesday, Henderson rode a bike during a voluntary practice session.

Ryan said it was premature to provide any timeline on when Henderson could be cleared for practice.

Henderson reported to the team's facility last week after having two operations, the first to remove diseased tissue and the other to re-attach the intestine.

A two-year starter, Henderson was diagnosed with having the inflammatory bowel disease late last season.
