Smith was struck by Rams defensive end Aaron Donald late in the third quarter, which resulted in an injury to his right throwing arm that forced him to leave the game.

According to Carroll’s description on Monday, Smith was struck “on the tendon on the bottom of his triceps.” The back of his arm was struck by the helmet at that point. That’s where he has a contusion. That’s the truth of the matter. Other than that, don’t believe there is any harm. However, we must observe the extent of its swelling. He received the best care possible because the doctors were monitoring him the entire flight, last night, and beyond.

Before making a comeback for Seattle’s last possession of the game, Smith missed the last two series in which he was injured and the first two series of the fourth quarter.

With 1:31 remaining, Smith returned to the game after the Rams had taken a 17-16 lead. He completed 3 of 5 passes for 36 yards, moving Seattle to L.A.’s 37-yard line, where Jason Myers missed a 55-yard range goal that would have won the game.

It was “a good sign that he could get back in and throw,” according to Carroll. was encouraging evidence of his functionality.

Carroll, though, issued a warning: “He’s going to be more sore today.” We’ll wait a few days to see how he reacts.

The 49ers, who defeated Tampa Bay on Sunday to go one game ahead of the Seahawks in the NFC West standings at 7-3, will play Seattle on Thursday night, capping a brief week for the team.

Smith responded, “We’ll see how it goes,” when asked if he will be able to play against the 49ers following Sunday’s game.

Smith went 22 for 33 for 233 yards and a score at the end of the game.

Smith was replaced by Drew Lock, who completed eight official snaps at 2-for-6 for 3 yards and one interception.

Carroll added that safety Jamal Adams could be able to participate despite being listed as inactive prior to the game due to discomfort in his surgically repaired knee.

Carroll answered, “I believe so.” “I really hope so. He simply needs to return at this point. I’m hoping that occurs so we can get him back into a healthy seven-day schedule.

Carroll was not questioned regarding the condition of running back Kenneth Walker III, who departed the game with a strained oblique after playing seven snaps on the opening series.

After the game, Carroll stated that although he was unsure about Walker’s length of absence or whether he would miss any time, “he’s sore, though.” I am aware of that. It was authentic.
