Overview

• Kyle Shanahan projects Brock Purdy as the starter with Mac Jones available as the Week 1 backup despite Jones’ recent knee sprain.
• Right guard Dominick Puni sustained a PCL strain and is uncertain for the opener, pressing options that include an elbow-limited Ben Bartch, Nick Zakelj or rookie Connor Colby.
• Receiver depth is strained with Jauan Jennings out since July 27, Brandon Aiyuk likely headed to the PUP list, and Demarcus Robinson expected to miss the first three games for a policy violation.
• San Francisco traded for Skyy Moore to bolster the position as injuries also sideline Jordan Watkins and stall Jacob Cowing’s progress.
• Rookies Mykel Williams and C.J. West have knee issues that cloud early usage, Upton Stout’s calf has opened nickel reps for Chase Lucas, and final roster calls arrive with the Aug. 26 cutdown.
