49ers RB Christian McCaffrey (back) will not practice on Tuesday.

30 December 2025

The 49ers will conduct a walkthrough today, though McCaffrey will not participate. 49ers head coach Kyle Shanahan told reporters that McCaffrey’s back is “a little stiff.” Trainers tended to McCaffrey’s back between drives, late in the fourth quarter during the 49ers’ Week 17 win over the Bears. He returned and played effectively. We expect him to do so this week as well, though backup RB Brian Robinson must be rostered wherever he is available.
