Injury Notes
Left tackle Trent Williams will miss his fifth straight game due to an ankle injury. His last appearance was on November 17 against the Seattle Seahawks.
Running back Isaac Guerendo has been ruled out due to the hamstring injury he sustained last week against the Los Angeles Rams. As a result, Patrick Taylor is expected to start against the Dolphins.
Defensive end Nick Bosa and linebacker Dre Greenlaw are questionable for Sunday's game. Bosa is dealing with hip and oblique injuries, while Greenlaw returned to the lineup last week after recovering from a torn Achilles.
Despite Greenlaw's listed status, head coach Kyle Shanahan told reporters that the linebacker has looked strong during practice this week.
Below are Friday's practice participation reports for both the 49ers and Dolphins, which were provided by the 49ers Communications staff.
