McCaffrey Questionable with Back Injury, Expected to Play Week 15

49ers RB Christian McCaffrey was added to the injury report Saturday with a back issue, making him questionable for Sunday's game against the Titans. Despite the designation, sources including Adam Schefter expect McCaffrey to play, as the injury is not considered severe. His official status will be confirmed 90 minutes before the 4:25 p.m. ET kickoff. If he faces a setback or snap count, Brian Robinson, Isaac Guerendo, and Jordan James would see increased roles.
