The Seahawks placed linebacker Bruce Irvin and safety Marquise Blair on injured reserve Wednesday, expected moves after Seahawks coach Pete Carroll confirmed on Monday that both had sustained season-ending ACL injuries in Seattle's Week 2 win over the Patriots.

With those roster spots open, the Seahawks promoted from the practice squad cornerback Linden Stephens and defensive tackle Anthony Rush. Guard/center Kyle Fuller is also back on the 53-man roster after being suspended for the first two games of the season. Additionally, the Seahawks put receiver Phillip Dorsett on injured reserve Tuesday

Carroll referred to the loss of Blair and Irvin as "a really a big blow. I know a lot of teams lost players this weekend; we certainly felt it with both of those guys. Both of those guys have a lot to offer your team in their attitude and approach and style of play, so it'll be difficult to replace those guys in that regard. We're going to miss those guys, I feel terrible for them. One guy at the start of his career, another is a guy has been through a lot of stuff in Bruce coming back around to us, it was really great to have him back. It's such a positive factor and such a great example of what our program is about, and I really loved him on this team. On the other side of it is Marquise just breaking in for the first time and getting it rolling and really making a big splash to start the season off with this. It's guys in different stages of their career, but yet they're both feeling it, and we're feeling the loss."

While Irvin and Blair's injuries will end their 2020 seasons, Dorsett won't necessarily be out too long. A change in IR rules this year allows players to return to action after missing only three games. The Seahawks have three games before their Week 6 bye, so this move will allow Dorsett at least four weeks to recover, then he could potentially return after the bye in Week 7.

Stephens, who first came to the Seahawks as a member of the practice squad last season, finished the 2019 season on Miami's active roster. When the Dolphins waived Stephens in April, the Seahawks claimed him. Stephens initially made Seattle's 53-man roster on cut day, but was waived a day later and then signed to the practice squad.

Rush, who signed with the Eagles as an undrafted rookie last year, signed to Seattle's practice squad after being released by the Eagles earlier this month, then was elevated from the practice squad for last week's game, playing 15 defensive snaps and recording two tackles. Rush appeared in nine games with the Eagles as a rookie, recording nine tackles, three tackles for loss and two passes defensed.
