What happened: Sunday's camp opener was conducted without pads, with coaching responsibilities divided among the staff. Kyle Shanahan is participating on a limited basis while recovering from injuries sustained in a July 14 car crash.
Why it matters: Foerster's familiarity with Shanahan's system gives San Francisco continuity during the temporary handoff. The assistant head coach is working with the coordinators rather than assuming every duty himself.
By the numbers: Foerster is entering his 34th NFL season and has worked alongside Shanahan for 13 seasons.
What to watch: Watch how long Foerster retains the expanded role and when Shanahan resumes full camp duties.
