Overview

• San Francisco has 21 days to activate Mustapha from the PUP list to the 53-man roster for him to be eligible to play this season.
• A return as soon as Sunday against the Buccaneers is possible if he is activated during the window.
• The second-year safety is coming back from January surgery to reattach a right‑knee ACL graft from a prior repair.
• Marques Sigle and Jason Pinnock have started the first five games at safety, with Ji’Ayir Brown playing base downs, including 12 snaps in Week 5.
• Coaches are evaluating package usage, with Pinnock deployed as a pass rusher and Sigle standing out in run fits despite coverage lapses.
