Troy Smith, who has yet to take a first-team practice snap with the 49ers, will be the team's starting quarterback Sunday against the Denver Broncos, coach Mike Singletary announced Wednesday morning.
Alex Smith is expected to miss 2 to 3 weeks with a left shoulder separation, Singletary said. David Carr has been demoted after struggling against the Carolina Panthers after taking over for Alex Smith. Carr completed 5 of 13 passes for 67 yards and a critical interception in the 49ers' 23-20 loss to the Panthers.
