The 49ers will not be with star wide receiver Brandon Aiyuk on Thursday night. Aiyuk suffered a left shoulder injury on his first catch against the Rams, when he landed hard on the turf at SoFi Field.

ESPN’s Adam Schefter reports Aiyuk will be out.

While he played through the injury on Sunday, he was limited for much of the game and was expected to have missed the first practice of this week. He was listed as limited in the team’s walkthrough on Tuesday, and with the abbreviated Thursday timeline always meant it would be a challenge for Aiyuk to play.

With that in mind, the team made two moves, including a reversal of a signing they made earlier this week at corner. It could be an opportunity for an increased workload for rookie Ronnie Bell.

The following comes from the 49ers:
