San Francisco 49ers head coach Kyle Shanahan revealed that quarterback Brock Purdy was a limited participant in practice on Wednesday while recovering from a toe injury, per Matt Barrows of The Athletic. Purdy suffered the injury in Week 1 and missed San Francisco's 26-21 win over the New Orleans Saints in Week 2. A potential return against the Arizona Cardinals in Week 3 would be an encouraging development for Purdy, as he was reportedly expected to miss between two and five weeks with the toe issue. ESPN's Adam Schefter reported Sunday that the 49ers weren't optimistic about Purdy returning against the Cardinals, but a Week 3 comeback was "not out of the question." The signal-caller has been relatively healthy since taking over under center for San Francisco, starting in 31 of a possible 34 regular-season contests across the past two years.
