SAN FRANCISCO (AP) -- Joe Nedney kicked a 29-yard field goal with 9:38 left in overtime, and Troy Smith passed for 356 yards while leading the San Francisco 49ers' late rally for a 23-20 victory over the St. Louis Rams on Sunday.

Smith earned his second straight victory as a starter for the 49ers (3-6), throwing a go-ahead 16-yard touchdown pass to Michael Crabtree with 2:10 left in regulation.

After Sam Bradford and Steven Jackson led the Rams (4-5) back for Josh Brown's 33-yard field goal on the final snap of
regulation, St. Louis couldn't get a first down after winning the overtime coin toss.

Smith swiftly moved the 49ers 55 yards, converting on third down for the first time in the game when St. Louis' Oshiomogho Atogwe was called for a 22-yard pass interference penalty.
