News: Dorsey has been placed on injured reserve due to a torn ACL.

News: Dorsey suffered a torn ACL in Sunday's loss to the Seahawks, according to NFL Network's Rand Getlin.
Impact: Assuming the diagnosis is confirmed by the team, Dorsey would presumably be headed to IR, with his looming absence representing a big blow to the 49ers' defensive line.

News: Dorsey went down early in Sunday's loss to the Seahawks with an apparent knee injury, and the team fears it could be an ACL injury, CSN Bay Area reports.
Impact: Dorsey had to be carted off the field, which is an ominous sign for any player who suffers a knee injury. A torn ACL would effectively end his season, and while it sounds like that may be what happened, we will wait for the MRI results Monday. If Dorsey is required to miss time, Arik Armstead should slide into the starting lineup.
