Overview
- Nick Bosa returned to limited practice on Wednesday after missing five games with a left calf strain, giving the 49ers a defensive boost as they prepare for the Raiders.
- The team opened 21-day injured‑reserve practice windows for WR Demarcus Robinson and CB Nate Hobbs on Wednesday so both veterans can be evaluated for activation.
- Christian McCaffrey, Mike Evans and Deebo Samuel did not practice Wednesday and remain day‑to‑day, with Shanahan saying McCaffrey could be limited in practice as early as Thursday.
- If McCaffrey is unavailable, rookie Kaelon Black would step in as the primary running back, and the club is keeping other short‑term depth plans ready while monitoring players’ practice participation.
- Brandon Aiyuk is applying for reinstatement and will be at the facility this week, a development that could prompt a release or trade decision as the 49ers balance health needs and the upcoming roster calendar.
