When the Seahawks host the Minnesota Vikings on Sunday night, they'll be without All-Pro safety Jamal Adams for the second week in a row, the result of the groin injury he suffered in Seattle's Week 3 win over Dallas.
"Jamal is still going to be another week away, unfortunately," Carroll said. "He's not going to make it back."
The good news for Adams and the Seahawks is that they have a Week 6 bye, giving him more time to work his way back and get fully healthy before the Seahawks play again in Week 7.
In more encouraging news for the secondary, cornerback Quinton Dunbar is expecting to practice this week in hopes of making it back from a two-game absence caused by a knee injury.
"Quinton went through the walk thru today, he'll practice tomorrow," Carroll said. "We'll see how that fits for him coming back. He's determined to try to get back for this ballgame, so we'll see what happens there."
Rookie linebacker Jordyn Brooks is unlikely to get back this week, the result of a knee injury sustained in Week 3 that kept him out of last week's game.
"Jordyn is still working on coming back," Carroll said. "He's not able to move around yet, so it's going to be hard for him to get back this week."
Running back Carlos Hyde, who missed last week's game with a shoulder injury, will again practice in a red non-contact jersey like he did last week, and could make it back this week, but like Adams he too could benefit from an extra break if the Seahawks hold him out ahead of the bye.
"He's going to practice all week like he did last week," Carroll said. "We're not going to get him hit during the week, so he'll be able to keep keep his timing and tempo and conditioning and all of that, and then if he feels good enough to do it, then we'll go. There's that big week coming up, the bye week can work in different ways for us as we as we try to project how to do this. So if he doesn't play, then he'll get two big solid weeks, and then the next week as we prepare too, and he'll be in great shape. We should come out of this bye really with a real boost for our personnel which we're excited about, but I know he wants to play right now so we'll see if we can get that done this week."
Cornerback Neiko Thorpe, who has missed the past two games, "has athletic hernia symptoms," Carroll said, which led to him being placed on injured reserve on Wednesday.
"He's been working hard to get back and he just can't get going," Carroll said. "… I'm not sure what the course will be."
With players able to come off of injured reserve after missing just three games this year, the Seahawks are hoping to get two players back from IR after the bye, defensive end Rasheem Green and receiver Phillip Dorsett.
On Green, who has been out since the season opener with a stinger, Carroll said, "There's a really good chance that that should happen. He's got a couple things he's got to get done, but he's working great and all the reports that that's likely to happen."
Dorsett, an offseason free-agent addition, has not played yet this year due to a foot injury, but the hope is for that to change after the bye.
"I just talked to Phil today, that's exactly what the plan is for that to happen," Carroll said. "So that's what we're shooting for."
