The 49ers had a walkthrough Tuesday and McCaffrey was listed as out with a back injury. 49ers head coach Kyle Shanahan told reports the 29-year-old running back’s back is “a little stiff.” Trainers tended to CMC’s back in the fourth quarter of the win over the Bears in Week 17, with McCaffrey returning to finish the game. With Lynch saying that he’s trending towards playing, fantasy managers can expect McCaffrey to be available in Week 18. Brian Robinson is the clear handcuff to roster if anything changes.
