Browns starting running back Willis McGahee is not practicing because of an unspecified injury.
McGahee, who was not on Wednesday's injury report, rode a stationary bike and worked with a trainer on the side of the field Thursday as the Browns continued preparing for Sunday's game in Green Bay. His injury is not yet known.
Cleveland signed McGahee on Sept. 20, a day after the Browns traded running back Trent Richardson to Indianapolis. McGahee has rushed for 164 yards and one touchdown since joining the Browns.
He gained 37 yards last week in a loss to Detroit, giving him 8,621 career yards, fourth most among active players.
If McGahee can't play, the Browns will likely start fullback Chris Ogbonnaya at tailback with Bobby Rainey and Fozzy Whitaker as his backups.
