Purdy Set To Practice Wednesday, Week 4 Return Possible

Brock Purdy is set to resume practicing Wednesday as the 49ers evaluate whether he’ll have limitations and can return Sunday against the Jacksonville Jaguars after missing two games with a turf-toe variant and a left-shoulder AC joint sprain; he was a limited participant last week. Backup Mac Jones aggravated a PCL knee sprain in Sunday’s 16-15 win over the Cardinals, is considered day-to-day, and finished 27-of-41 for 284 yards, one touchdown and one interception while going 2-0 as a starter. Demarcus Robinson’s suspension was lifted and he is eligible for team drills under a roster exemption through Wednesday, and the team has not yet filled the roster spot opened when Spencer Burford went to injured reserve. Defensive tackle CJ West will undergo surgery for a broken thumb but could play Sunday with a cast, and Mykel Williams and Renardo Green are listed day-to-day after finishing the game. Coach Kyle Shanahan said Purdy’s practice availability and any limitations this week will determine who starts in Week 4.
