Dobbs was the first backup quarterback to enter Sunday's exhibition contest for San Francisco.
Dobbs wound up completing 57 percent of his passes for 133 yards and a rushing touchdown. Fellow backup Brandon Allen started the last preseason contest ahead of the Passtronaut, but the players reversed roles while serving as the reserves against the Saints. Brock Purdy (2-for-6, 11 yards) is the unquestioned starter despite some rusty throws Sunday, but Dobbs may have leaped ahead of Allen based on both production and usage as Week 1 approaches.
