The Seahawks earned a big victory over the New England Patriots on Sunday night, but they lost two key pieces of the defense for the rest of the season.

Strongside linebacker/pass-rusher Bruce Irvin and safety Marquise Blair, the team's No. 1 nickel defensive back, both sustained ACL injuries in Sunday's 35-30 win over the Patriots and will need season-ending surgery.

"Both Bruce and Marquise are going to have to have surgery, so that means that they will be done for the season, which is really a big blow," Seahawks coach Pete Carroll said. "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."

Carroll did note that players stepped up to fill in for their injured teammates, most notably second-year defensive back Ugo Amadi, who had eight solo tackles, one for a loss, taking over the nickel role. The Seahawks have several options to take over at strongside linebacker for Irvin, including second-year 'backer Cody Barton, who started games there last year in place of an injured Mychal Kendricks, and possibly 2020 first-round pick Jordyn Brooks, who so far has worked primarily at weakside linebacker, seeing limited playing time in the first two games in place of starter K.J. Wright. Shaquem Griffin, who spent most of training camp as the No. 2 strongside linebacker behind Irvin, is still with the team on the practice squad so he could be a consideration as well.

The picture at the nickel spot is clearer, with Amadi stepping into that role, which he held late last season before Blair was able to win it in camp this year.

"He did well, he did a nice job," Carroll said. "He really was active—ever since he's been on the field force in special teams and when he plays (on defense), he just shows up. He's got great burst to get to the ball, a very active football player—he just missed breaking that pass up, really he had his hand on the ball and didn't get the ball knocked out on a third down. He's way ahead of where he was last year when he was just barely getting going, so as he comes back to us, we won't have any restrictions on what we can do, and we look forward to his input. We need him to step up and be a factor. He's filling some big shoes, Marquise really had done a great job to this point, so we're calling on him—he's going to play a little bit different, a little different style to him—but we're really counting him to come through."

Other Injuries

Pete Carroll said defensive end Rasheem Green (neck) and tackle Cedric Ogbuehi (pectoral) both have a chance to get back this week after missing Sunday's game, but the status on both won't be known until later in the week.

"Rasheem Green will be evaluated Wednesday, we'll take one day at a time," Carroll said. "If he's back or not, we'll have to wait and see on that one… Cedric Ogbuehi, he has a chance to get back this week. We've got to wait and see how he responds. We'll start on Wednesday figuring it out and then working our way through it. He and Rasheem are kind of in the same boat that we have to wait and see how those guys respond. Phillip is not part of this game plan coming up, we're going to rest him for sure."

Receiver Phillip Dorsett II will miss at least a third straight game due a foot injury, and could be out longer, Carroll said. Dorsett has practiced some over the past two weeks and was listed as questionable for Sunday's game, but now will be given some time off to let the injury heal.

"Phillip Dorsett, we're looking to figure out how to work this out," Carroll said. "We need to give him a break to make sure that his foot is healed and back. He tried to get back this week to play in this past game and couldn't do it, so we have to give him more time in that. We have to consider what we're doing with that."

Left tackle Duane Brown briefly left the game but quickly returned and was able to finish the game.

"You saw Duane Brown, he did get a look at his foot," Carroll said. "I don't know what the injury is, but he had a sore foot coming out of the game, and I don't know the extent of the injury in that."

Safety Jamal Adams and cornerback Tre Flowers both dislocated fingers in the game but were able to return to action and Carroll said those injuries shouldn't be a problem going forward.
