49ers Brock Purdy Expected Ready Week 4 After Beating Injury Timeline

San Francisco 49ers quarterback Brock Purdy is nearing a return after missing two games due to a turf toe and shoulder injury, with head coach Kyle Shanahan indicating Purdy was expected to resume practice and possibly be ready by Week 4 against the Jacksonville Jaguars. Backup quarterback Mac Jones has filled in admirably during Purdy's absence, leading the team to a 3-0 start despite his own knee injury concerns. Purdy's turf toe injury, initially feared to sideline him for up to five weeks, has progressed better than anticipated, making his comeback likely soon. The 49ers have faced multiple injuries this season, including season-ending loss of Nick Bosa, and absences of Brandon Aiyuk and George Kittle, making Purdy's return crucial. The team elevated quarterback Adrian Martinez from the practice squad, which may affect Purdy's backup status, partly due to the NFL's "Emergency Third Quarterback" rule implemented after prior injuries to 49ers quarterbacks. Shanahan and analysts remain cautiously optimistic about Purdy's ability to return to game action soon, viewing his ability to practice as an encouraging sign despite the challenges of managing turf toe injuries.
