ORCHARD PARK, N.Y. -- James Cook returned to practice Tuesday amid his contract dispute with the Buffalo Bills , appearing to at least pause the star running back's hold-in.

Cook was in full uniform and began the session fully participating. He did not participate in the last four days of practice and also missed Buffalo's first preseason game.

Bills coach Sean McDermott said he expected Cook to return to practice earlier Tuesday, adding that "things have changed."

"We've had conversations with James," McDermott said. "Good conversations, as I've mentioned before, and the information that we're getting is that he is moving in the direction of practicing today.

McDermott declined to answer whether Cook's hold-in is officially over.

Cook, 25, took the field in full uniform Saturday
