Overview

• Brock Purdy practiced Wednesday and Thursday in a limited capacity and said his toe recovery remains day to day ahead of the Cardinals game.
• Kyle Shanahan called Purdy’s limited work a real good sign and said the quarterback has a chance to play, with medical staff making the final call.
• Both Purdy and backup Mac Jones addressed reporters this week, an uncommon setup that underscores unresolved starting plans.
• Jones delivered 279 yards and three touchdowns in the Week 2 win over the Saints, giving the 49ers confidence if Purdy cannot go.
• Tight end George Kittle is on injured reserve, and wide receiver Jauan Jennings’ availability is uncertain after shoulder issues despite returning to the practice field.
