Pace has concussion; Tinoisamoa dislocates elbow
Pace, the seven-time Pro Bowl lineman and former No. 1 overall draft pick, didn't return after getting hit on the head during the Rams' final drive of the first half. Pace, who missed just nine games in his first nine NFL seasons, was replaced by right tackle Todd Steussie the rest of the way, with Adam Goldberg filling in for Steussie.
"He got hit in the head and wasn't able to come back in," Rams coach Scott Linehan said. "I did briefly talk to him at halftime. He wasn't feeling too good then. But no excuses. [The 49ers] had injuries, too, in their line. We just weren't able to come out in the second half and perform like you need to perform to win on the road."
Tinoisamoa, a consistent starter for the Rams in his first three seasons, did not return to the game but could rejoin St. Louis in practice this week.
"I think the idea is once we evaluate it and treat it, that he should be available next week," Linehan said. "It's too early to say."
Justin Smiley, San Francisco's starting right guard, sprained his left shoulder.
