Overview

• Mustapha logged about 20 defensive snaps in the Week 6 loss to the Buccaneers, and Kyle Shanahan said he looked good and flew around.
• Ji'Ayir Brown replaced Jason Pinnock in the starting lineup and played every defensive snap, while Mustapha and rookie Marques Sigle split the other spot.
• Jason Pinnock did not play on defense, appearing only on special teams after starting the first five games.
• Shanahan said Mustapha is expected to be a full-time starter soon, with the team planning to increase his workload in the coming weeks.
• The starting role next to Mustapha remains unsettled as Shanahan continues evaluating Brown, Sigle and Pinnock heading into Week 7 against the Falcons.
