San Francisco 49ers coach Mike Singletary will make another switch at the quarterback position, going back to his original signal-caller to start the season.
With his injured shoulder recovered, Alex Smith, who started the 49ers' first seven games this season, will replace Troy Smith as the team's starter Sunday against the Seattle Seahawks, according to a source with knowledge of the situation.
Backup Troy Smith has been the Niners' starting quarterback the last five weeks, guiding the team to three wins and a pair of losses. In five games as the 49ers' starter, the former Heisman Trophy winner from Ohio State has posted four touchdowns, three interceptions and 1,023 passing yards.
Alex Smith recorded nine touchdowns and nine interceptions with 1,554 passing yards in seven games before injuring his shoulder in Week 7.
