The outlook leaves their Week 4 availability open. ESPN's Nick Wagoner reported that Evans went out in the second quarter and was ruled out for the remainder of the game at halftime. Williams left in the third quarter, returned to the sideline and watched Vederian Lowe finish at left tackle. Greenlaw tried to return for a play before the team shut him down.
Those are three separate decisions for the week ahead. Evans is dealing with a rib issue after his practice workload was managed for a hip injury last week. Williams's progress will affect the protection in front of Brock Purdy, while Greenlaw's recovery affects the defensive lineup. The favorable initial assessment still requires the players to progress through the week.
There is also a difference between returning to practice and becoming available for a game on the defensive line. San Francisco plans to open Mykel Williams's practice window Wednesday, but Wagoner reported that he cannot play until Week 5 because he began training camp on the physically unable to perform list. Williams is returning from a torn right ACL.
