What happened: San Francisco 49ers running back Christian McCaffrey is dealing with muscle tightness, but the injury is not considered serious. Head coach Kyle Shanahan noted he would have participated in Tuesday's practice if it were not a joint session against the Los Angeles Chargers.

Why it matters: The absence prompted immediate attention during the preseason schedule. Shanahan previously dismissed rumors that the time away was related to a new contract, and McCaffrey's fantasy value remains unchanged following a dominant 2025 campaign.

What to watch: The 49ers continue their preseason schedule as they manage his workload.
