Overview

• Official reports list Brock Purdy as a non-participant Thursday because of a toe injury, and multiple outlets report he is expected to miss a fourth game at Tampa Bay.
• Mac Jones was limited with knee and oblique issues and did not throw Thursday, with Kyle Shanahan saying he should be ready Sunday; Jones is 3-0 with 905 yards, six touchdowns and one interception as a starter.
• General manager John Lynch provided no firm timetable for Purdy’s return and reiterated that Purdy will reclaim QB1 once healthy.
• Practice-squad quarterback Adrian Martinez remains the only other option on the roster, highlighting thin depth if Jones suffers a setback.
• Jauan Jennings returned to practice in a limited capacity, Ricky Pearsall did not practice, and George Kittle remains out as the 4-1 49ers manage a lengthy injury list.
