Torrey Smith out vs. Falcons, Joe Staley doubtful

SANTA CLARA -- Wide receiver Torrey Smith is out for Sunday’s game against the Falcons while left tackle Joe Staley (hamstring) is doubtful for his second straight game.

That means the 49ers offensive line likely will be composed the way it was to end Sunday’s game against the Jets: LT Zane Beadles, LG Andrew Tiller, C Marcus Martin, RG Joshua Garnett and RT Trent Brown.

It’s not known who will start in place of Smith, who lost consciousness when his head slammed to the ground in the third quarter Sunday. Smith said he was feeling better but that he can’t remember much of what happened after receiving the play call on the snap on which he was injured. He will not fly to Atlanta with the team.

Rookie Aaron Burbridge started the last time Smith missed a game in Week 11, but Chris Harper ended playing more snaps (34) in that contest than Burbridge. Harper also got most of the snaps after Smith left Sunday’s game.

Burbridge (hamstring) was a full participant in Friday’s practice. So were quarterback Colin Kaepernick (neck), who appeared on the injury report on Thursday, and defensive lineman Quinton Dial (elbow), who missed two of the team’s last three games.
