Bosa (ribs) has been deemed questionable to play Week 3 versus the Rams, Matt Barrows of The Athletic reports.
San Francisco coach Kyle Shanahan explained Friday that Bosa suffered a rib injury during practice this week, per Jennifer Lee Chan of NBC Sports Bay Area. The issue resulted in the star defensive end being held to limited sessions Thursday and Friday. If Bosa were to miss the 49ers' Week 3 game, Yetur Gross-Matos and Robert Beal could be asked to step up with increased workloads on defense.
