Overview

• Head coach Kyle Shanahan confirmed Purdy will start Sunday at Levi's Stadium after toe and non-throwing shoulder issues kept him out of Weeks 2 and 3.
• Purdy practiced in limited fashion throughout the week and carried no injury designation on Friday, indicating full readiness.
• Backup Mac Jones, who won both interim starts, is listed as questionable with a knee injury, with practice-squad QB Adrian Martinez a possible elevation if needed.
• The final injury report lists WR Jordan Watkins and DT C.J. West out, with Jauan Jennings, Ricky Pearsall, Connor Colby and Renardo Green questionable.
• Defensive coordinator Robert Saleh said Jacksonville is adept at legally decoding signals, a tactical wrinkle against a defense ranked fifth in points allowed.
