Isaac Guerendo, Nick Bosa, Trent Williams won’t practice Tuesday

49ers head coach Kyle Shanahan shared his team's pre-practice injury report at a Tuesday press conference and it was the same as Monday's estimated one, so several key players are on the sideline ahead of Thursday's game against the Rams. Shanahan said that running back Isaac Guerendo (foot), left tackle Trent Williams (ankle), and defensive end Nick Bosa (hip, oblique) will not take part in the team's Tuesday practice. Williams and Bosa have missed the last three games while Guerendo was injured late in last Sunday's win over the Bears. Patrick Taylor and Israel Abanikanda are the other backs on the 53-man roster with Ke'Shawn Vaughn on the practice squad. Guard Ben Bartch (ankle) will also miss practice and he is set for injured reserve. Linebacker Dre Greenlaw (Achilles), defensive end Yetur Gross-Matos (knee), safety Malik Mustapha (chest, shoulder), linebacker Dee Winters (ankle), and linebacker Demetrius Flannigan-Fowles (knee) will be limited participants.
