Bosa (rib) is listed as questionable but is expected to play Sunday versus the Rams, Adam Schefter of ESPN reports.
Bosa was added to the 49ers' injury report Thursday and was a limited participant in the team's final two practices of Week 3 prep, but he looks as though he'll be ready to play Sunday, though perhaps at less than 100 percent health. He has accrued seven tackles and two sacks through the 49ers' first two contests.
