Nick Bosa, Trent Williams, Isaac Guerendo estimated as non-participants Monday

49ers defensive end Nick Bosa (hip/oblique) and left tackle Trent Williams (ankle) remain out of practice on Monday's estimated report.

Coach Kyle Shanahan said the team will evaluate Bosa and Williams this week with the possibility of one or both returning Thursday night.

Running back Isaac Guerendo also was estimated as a non-participant after injuring his foot Sunday. The 49ers have not ruled him out to play against the Rams.

Offensive lineman Ben Bartch, who is headed to injured reserve with a high-ankle sprain, was the other player estimated as out of practice.

Linebacker Dee Winters (ankle), safety Malik Mustapha (chest/shoudler), linebacker Demetrius Flannigan-Fowles (knee), linebacker Dre Greenlaw (Achilles) and defensive end Yetur Gross-Matos (knee) were listed as limited.

Offensive lineman Aaron Banks has cleared concussion protocol and was listed as a full participant.
