There's a chance McCaffrey (Achilles) will run on hard ground this coming week, Ian Rapoport of NFL Network reports.
McCaffrey, who is dealing with Achilles tendonitis, remains on IR and without a clear timetable for a return, but Rapoport suggests that the running back should be back, at least, by early November. In the meantime, Jordan Mason is on track to lead the 49ers' backfield while McCaffrey remains sidelined.
