While one of Seattle's Pro-Bowl safeties, Jamal Adams, was lost for the season last weekend, another, Quandre Diggs, will be able to play on Sunday despite being listed as questionable for the Seahawks' Week 14 game at Houston.

Diggs, who leads the team with four interceptions, didn't practice Wednesday or Thursday due to a calf injury and was listed as questionable on Friday's injury report, but Seahawks coach Pete Carroll said, "He's going. He feels fine. He missed time so that we could rest him to make sure, but he's determined to play, so I'm not even thinking about it."

As for Adams, who was placed on injured reserve Friday, Carroll confirmed that the Pro-Bowl and All-Pro safety had his surgery this week and said early reports on the procedure were positive.

"The early indications are they really worked hard to make sure that this is going to be secure and all that and took some steps to do that," Carroll said. "I haven't talked to him yet since the surgery, but we got really good reports on what they did."

In addition to Adams, the Seahawks will be without three players who have been ruled out, right tackle Brandon Shell, running back Travis Homer and guard/center Kyle Fuller.

Shell has been dealing with a shoulder injury for multiple weeks, and Carroll said the hope is that missing a game helps him down the stretch. He will be replaced in the lineup by one of two rookies, Stone Forsythe, who finished the game in that spot last week, or Jake Curhan, who had already come into the game at guard to replace Fuller by the time Shell left the game.

"Jake has played on the right side for us and Stone can play there, as well," Carroll said. "Brandon, he's been hanging in there with a shoulder that's just been a bother to him, and we've just got to give him a break this week and see if we can get him stronger for the finish of the season."

While not on the injury report because he is on the practice squad, running back Adrian Peterson will also be out this weekend—the Seahawks could have elevated him again from the practice squad—due to a back injury.

"He had a lower back issue that came up, and he felt it a little bit coming into Wednesday, and then on Wednesday he couldn't go," Carroll said. "We're going to hold him out. We're got to take care of him and look after him."

The Seahawks will be getting two players back who did not play last week due to injury, left guard Damien Lewis, who has missed the past two games, and running back Alex Collins, who has been dealing with an abdomen injury for much of the season.

On Lewis, Carroll said, "He didn't miss a snap all week. He took everything, and it's great to have him back out there. Just feels like it's supposed to feel. He's such a good football player, and as he's growing into… It just feels good to have him out there. He missed nothing. He means something to us because he's been a starter and he's been working hard at it, and he's tough and all that, and so it just helps us continuity-wise. It's a good deal for us."

On Collins, Carroll said, "The last couple weeks Alex was preparing by really holding back during the week and then letting it go on the weekend. This week he didn't have to do that. He was able to practice fast and hard and get his reps in because just missing that game just gave him a boost. He should be back to normal and back to full flow and all that. I know he's excited about coming back. He hated that he missed a game. We kind of had to do it. He wouldn't have chosen not to play, he wanted to go, and we had to do it to try to rest him and give him a little bit of a jump for this finish of the season coming up."
