Christian McCaffrey Has Tendinitis In Both Achilles

49ers RB Christian McCaffrey has been dealing with tendinitis in both Achilles, according to NBC Sports Bay Area's Matt Maiocco. It's still unclear when he started having these issues (it was reported as a calf injury all August) but helps explain why McCaffrey has had so much trouble getting on the field. McCaffrey is expected to ramp up his rehab this week, although it sounds like Week 10 is his likeliest date to return to game action.
