Mike Singletary finally confirmed what many have suspected: Troy Smith will be the 49ers' starting quarterback when they face the St. Louis Rams on Sunday.
The coach made the announcement on Friday, according to *The Sacramento Bee*.
Alex Smith continues to rehab his separated, non-throwing left shoulder, injured in a loss at Carolina on Oct. 24. The Bee reported that Smith had an impromptu end-of-practice throwing session with receiver Jason Hill on Friday.
David Carr will serve as San Francisco's backup quarterback. Singletary will go without a No. 3 quarterback for the second consecutive game.
Troy Smith rallied the Niners to a 24-16 win over the Broncos in London on Oct. 31 -- and the team certainly wants to see if he can do it again. San Francisco is coming off its bye week.
The Rams, like the 49ers, are mostly healthy heading into Week 10. Wide receiver internal-link-placeholder-2 and safety James Butler (ankle) are the only players listed on the injury report as out. Tight end Fendi Onobun (back) is listed as doubtful.
