The Seahawks host the AFC North-leading Baltimore Ravens at CenturyLink Field Sunday, and while head coach Pete Carroll really likes what he saw from his team in its preparation this week, the Seahawks could be missing a few key players when the game kicks off.

"This has been a great preparation" Carroll said. "These guys really dived into this thing with the right mentality. We're hoping that by the time we get through the review (Saturday) that they're going to be ready to roll. It takes all week to get ready for a team like this. It takes a championship performance in the practices to get it done. We really like what's happening so far. You'll see that there are still some guys that are questionable here. We're not sure on some guys all the way until game time. We're ready to roll. It's a good matchup."

Questionable for Sunday are safety Bradley McDougald, who did not practice all week due to a back injury, left tackle Duane Brown, who missed last week's game with a biceps injury, defensive end Ziggy Ansah, who injured his ankle making a key play in last week's game, guard D.J. Fluker, who was out last week with a hamstring injury, and defensive end Quinton Jefferson, who was limited in practice Thursday and Friday due to an oblique injury. Out for the Seahawks is tight end Will Dissly, who sustained a season-ending Achilles injury last weekend. Safety Lano Hill is officially listed as doubtful with an elbow injury, though Carroll said he won't play.

With Hill sidelined, if McDougald isn't able to play, that will mean rookie Marquise Blair would make his first start at safety alongside Tedric Thompson.

If Blair does get the start, Carroll said, "I want him to kick butt. I'm counting on him playing really good. He's a runner and a hitter. He has shown that. We don't have any question about that. It's just, can he settle in and be comfortable with the calls and adjustments and all that stuff and just play good ball? There's no question about his ability level; it's just getting acclimated. He's had a really good week of practice. He's got a ton of work because of the situation with the safeties. This is as ready as he could possibly be at this point right now. We're looking forward to him playing if that's the call."

Here is what Carroll said about the some of his team's injured players:

S Bradley McDougald

"He came out Tuesday. He woke up with back spasms. We're just dealing with that. He's not right today. Couldn't go today, yet. This is the kind of thing, it's not an injury, it's more of a condition. He might be able to pop out of this. We'll see."

S Lano Hill

"He's going to be out. He's not going to make it. He will not make it. He's got a thing in his elbow that's going to take a couple weeks here before we know what we can do with it."

DE Ziggy Ansah

"He's questionable. He was going to try to get out there today. He couldn't quite get out there today but, he did some stuff. We're going to take him right up to game time."

Carroll said the injury happened "on the play where he forced the fumble… On the return he got tangled up and twisted pretty good and they fell on it. He had a nasty little twist on it."

G D.J. Fluker and T Duane Brown

"Fluke practiced today, Duane did not. Fluke's looking pretty good, and we'll see. We're going to wait all the way up until game time with Duane."

DT Jarran Reed

While not injury related, it's worth noting that Carroll said defensive tackle Jarran Reed is ready to play Sunday after returning from suspension this week. The Seahawks will have to make a roster move to add Reed to the 53-man roster ahead of Sunday's game.

"He must have worked really hard. He would tell you that he did," Carroll said. "The challenge of the practice was nothing for him. He'd been working hard enough so that this is not a step up for him, which is what you hope so that he doesn't have a fall out coming off the practices. He's ready to go."
