Nick Bosa questionable, Trent Williams ruled out for Thursday night

The 49ers may have Nick Bosa back for Thursday’s matchup against the Rams, but they will not have left tackle Trent Williams.

San Francisco has listed Bosa (hip, oblique) as questionable for the contest. He was listed as a limited participant in Wednesday’s walk-through.

Bosa has missed the last three games.

Williams, however, has been ruled out. He’ll miss his fourth straight game with an ankle injury.

Guard Ben Bartch (ankle) and safety Malik Mustapha (chest/shoulder) have also been ruled out.

Running back Isaac Guerendo (foot), defensive tackle Khalil Davis (knee), and linebacker Dre Greenlaw (Achilles) are all questionable. San Francisco will have to activate Greenlaw to the 53-man roster for him to play. Guerendo was a limited participant and Greenlaw was a full participant on Wednesday.
