Bosa (knee) was limited in Tuesday's practice, Matt Maiocco of NBC Sports Bay Area reports.
Bosa is nearly a full year out from ACL surgery, and defensive coordinator Raheem Morris has already said the star defensive end will play in Thursday's season opener against the Rams. Bosa has played only 17 regular-season games over the last two seasons combined, but the 28-year-old recorded 11.0 sacks in those contests.
