Christian McCaffrey Cleared for Full Workload in Week 18

49ers RB Christian McCaffrey (back stiffness) has no injury designation for Saturday's pivotal game against the Seahawks, confirming his availability and expected full workload. After missing Tuesday's practice and being limited Wednesday, he was a full participant Thursday and is now cleared for Week 18. McCaffrey, who has 17 touchdowns and over 2,000 scrimmage yards, is crucial for the 49ers' #1 seed pursuit and NFC West title. He is just four catches shy of his third career 100-reception season.
