San Francisco 49ers running back Christian McCaffrey misses Monday’s training camp practice, with multiple outlets reporting he does not take part due to “tightness.” Coverage notes he joins other players on the sideline rather than working on the field.

The 49ers characterize the issue as general tightness and indicate they are not overly concerned at this stage, with at least one report suggesting the team is managing McCaffrey’s workload. Other outlets highlight that the absence could signal another injury-related consideration during camp, though they also frame it as an early, limited development.

Overall, the reports align on the basic facts: McCaffrey sits out his first practice of the session, the reason given is tightness rather than a specific diagnosis, and the team’s approach is to monitor him and manage his participation.
