Overview

• Brock Purdy was limited in practice all week and is listed as questionable, saying he likes his progress and will see about Sunday.
• Kyle Shanahan said Purdy’s toe is improving day by day and indicated he could play if the progress continues, with a firmer read expected after final evaluations.
• Mac Jones remained limited with a knee issue he aggravated in Week 3, telling reporters he feels good and expects treatment to have him ready.
• Practice-squad quarterback Adrian Martinez, the 2024 UFL MVP and Jones’s recent backup, took first-team reps and would start if Purdy and Jones cannot go.
• The 49ers have not added another quarterback this week, which reporters view as a sign of confidence that at least one of Purdy or Jones will be available against Jacksonville at Levi’s Stadium.
