49ers vs. Rams: Is there a quarterback controversy after pseudo-comeback?

The San Francisco 49ers tied with the St. Louis Rams, 24-24, on Sunday and had to play two quarterbacks after Alex Smith left the game in the second quarter with a head injury that was later ruled a concussion.

Colin Kaepernick replaced Smith after he threw a 14-yard touchdown pass to Michael Crabtree that cut the Rams' lead to 14-7 with 8:13 left in the second quarter.

Kaepernick said he "did pretty well" which may result in a quarterback controversy after Smith is cleared to play, according to Ray Ratto of CSNBayArea.com. Given Smith's record as the starter, Ratto says that there should not be a controversy but it is a conversation that will occur in the coming weeks.

Smith was 7-of-8 passing for 72 yards and one touchdown in the game. Kaepernick was 11-of-17 for 117 yards in place of Smith.

San Francisco head coach Jim Harbaugh said Smith will undergo further testing on Monday and his status for next week's game versus the Chicago Bears is uncertain.
