Overview

• The 49ers listed Brock Purdy as a limited participant Wednesday with left shoulder and toe injuries, and Shanahan said he has a chance to play against the Cardinals.
• If Purdy is not cleared, Mac Jones would start after a 26-of-39, 279-yard, three-touchdown, zero-interception debut in a 26-21 win at New Orleans.
• San Francisco placed starting left guard Ben Bartch on injured reserve with a high ankle sprain, and rookie Connor Colby is expected to step in at the position, per ESPN.
• Eight players did not practice Wednesday, including Spencer Burford, Jauan Jennings, Kyle Juszczyk and Siran Neal, with rest days for Nick Bosa, Christian McCaffrey and Trent Williams.
• The team promoted tight end Brayden Willis to the active roster and added offensive lineman Brandon Parker to the practice squad, as outside commentary debated the value of Purdy’s past production in Kyle Shanahan’s system.
