The 49ers still haven't decided who will start at quarterback against the Broncos in the team's preseason opener. San Francisco coach Mike Singletary said that he may wait until Thursday to choose between Alex Smith and Shaun Hill. "We'll talk about it prior to the game, figure it out," Singletary said Monday, according to the Associated Press. "We're in no rush to do that." The 49ers will battle the Broncos on Friday.
