Christian McCaffrey returns to 49ers practice after lengthy IR stint. The running back has been recovering from Achilles tendinitis in both legs and is expected to make his season debut on Sunday against the Tampa Bay Buccaneers, pending a smooth week of practice. McCaffrey's absence has been felt in the passing game and red zone, but teammates Jordan Mason and Isaac Guerendo have stepped up in his place.
