Linebacker Jamie Winborn cleaned out his locker and left the San Francisco 49ers on Wednesday as the club abruptly announced plans to trade the former starter. Winborn lost his job to converted defensive end Andre Carter last week, and coach Mike Nolan suggested the fifth-year pro should stay away while the 49ers find him a new home. "He sees himself as a starter, and I would tend to agree with that," Nolan said. "It just won't be here."
