49ers defensive lineman Glenn Dorsey suffered a torn ACL

Glenn Dorsey might have played his last snap for the 49ers this season.

SANTA CLARA, Calif. - 49ers defensive tackle Glenn Dorsey hobbled through the locker room following Sunday's 29-13 loss in Seattle on crutches after getting carted off the field after one play. His prognosis did not look good.

The 49ers announced Monday it was a torn ACL in his right knee.

Dorsey went down on the Seahawks' first play of scrimmage after taking minimal contact, appearing as though he suffered a significant injury for the second straight season.

Dorsey missed all of last season after suffering a torn biceps tendon during training camp.

Without its starting defensive tackle, San Francisco allowed a team record 209 yards rushing to back up running back Thomas Rawls, while Seattle notched a season-high 508 yards of offense after failing to eclipse 388 yards in any of their previous nine games.

"I think, Glenn going down early, I think that really hurt us. And I think Rawls wanted to prove himself to the Seattle Seahawks today, so he came out there with a little chip on his shoulder," NaVorro Bowman said after the game. "But anyway, we have to play better, we have to tackle better. And if we do that, this game would have been a lot better."

Dorsey's absence meant increased snaps for the team's most recent first-round pick Arik Armstead, who has been used mostly in passing situations this season. Armstead played 46 snaps, tied with Ian Williams for the second most among defensive lineman. Quinton Dial played 62 snaps.

Sunday, the 49ers will host the first-place Arizona Cardinals, who are coming off wins against the Seahawks and Bengals, and have the league's second-ranked offense led by quarterback Carson Palmer and a balanced running game.

Tomsula hopes his team can rebound and avoid falling to 3-8.

"You believe in the people that you have. That locker room and the guys that are in it. There’s good, determined, good football players in there. We’ve got to just keep pounding through it and get to the other side," Tomsula said.
