Seahawks safety Kam Chancellor will be a gameday decision after not practicing all week, the result of a pelvis injury suffered in last week's win at Baltimore.
"He's questionable right now," Seahawks coach Pete Carroll said. "We'll wait all the way up to game time to see if he can bounce back from this thing."
Despite the lack of practice this week, Chancellor is a player who, given his experience level, could be ready for a game without practicing should he be able to go physically.
"He really could," Carroll said. "He could jump in and play."
Chancellor suffered his injury early in last week's win at Baltimore and was replaced by Kelcie McCray for the rest of the game. If Chancellor can't play, McCray would make his first start of the seasons, and Carroll said he was happy with what he saw out of McCray in relief of Chancellor last week.
"I was really fired up about him because he played right," Carroll said. "He was in the right spots, he saw things correctly, he fit in the running game, and in the pass game really well. He played fast, and he tackled well when he had his chances. He had two plays from having a phenomenal game. Both were about this far on third down plays. He made the tackle right at the sticks, and both spots were first downs. They were like 2-yard plays. We're asking for a little bit better there. He was on all of that. He did a very good job for us, and he did well on the deep end, in the middle too. We didn't have to change anything, we didn't adjust anything. We just played with him, and as we saw him, that gives us really a lot of confidence going into this week in case Kam can't play. It was a really good performance by him."
McCray, who came to Seattle in a preseason trade with Kansas City, has been one of the team's top special teams players all season, but would love another shot at showing what he can do on defense should he end up starting Sunday.
"It feels good, and hopefully I can go out there and show them what I really can do and prove them right for bringing me here," McCray said.
And if McCray is the starter, he'll benefit from an entire week of practicing as the starter, unlike last week when he had to unexpectedly jump in for Chancellor in the middle of a game.
"It's great having the full week," he said. "I get all the looks, so it's not a surprise to me going into the game. I definitely feel like I've had all the looks this week, so it's definitely a big help."
Despite being listed as questionable, Carroll gave good news on cornerback DeShawn Shead, who returned to practice Thursday from an ankle injury and practiced fully on Friday.
"He's going to play," Carroll said. "He's fine. He made it through the week and he had a good day again today. He, like Luke (Willson), I don't know how they got back so fast. I don't know how they did it, but they did and they're ready to go. They practiced enough to show all of that."
As Carroll mentioned, tight end Luke Willson is expected to play this week after suffering a rib injury at Baltimore, another case of Willson coming back quickly from an injury, something he has done on multiple occasions in his career.
"He continues to just amaze us at how he comes back," Carroll said. "He got hurt pretty good and he didn't miss even a walkthrough or anything. He got all the work done this week, so he's going."
Running back Marshawn Lynch (abdomen), tight end Anthony McCoy (knee/ankle) and defensive tackle Jordan Hill (toe) have all been ruled out. Carroll said McCoy has a high-ankle sprain, while Hill, who will miss a third straight game, has a chance to get back to running next week. Everyone else on the injury report is listed as probable, indicating that they should be available for normal duty.
