The Seahawks will be without one of their top players when they host Washington on Sunday, with free safety Earl Thomas ruled out due to the hamstring injury he sustained late in last week's win over Houston.

"We weren't able to get enough done, so he's out for this one," Seahawks coach Pete Carroll said following Friday's practice.

But while the Seahawks will miss the All-Pro safety on the back end of their defense, they are very confident in his replacement Bradley McDougald, an offseason free-agent signing who was a starter the past two seasons in Tampa Bay.

"He's ready to play, he knows everything, he communicates beautifully with our guys," Carroll said. "He has been on the field a lot, so it really doesn't feel like newness. You're going to miss Earl just because Earl is Earl, but Bradley will do a really good job."

On a more positive note, strong safety Kam Chancellor returned to practice after being held out the previous two days with an ankle injury, and is "fine" according to Carroll despite being listed as questionable.

Bobby Wagner also returned to practice after missing the previous two days with a hamstring strain.

"We're going to just make sure tomorrow and see how he feels all the way up to game day, because he just practice Friday," Carroll said. "… He had a little hamstring strain that we wanted to make sure won't keep him out, so we rested him, and he practiced today, did fine today. We'll see how he comes back from it tomorrow, then we'll wait all the way up to game day."

Defensive tackle Sheldon Richardson, who sustained an oblique injury in practice this week, did not practice Thursday or Friday and is questionable for Sunday.

"We've got to wait until game day to make sure he's OK," Carroll said. "He got a little oblique strain."

Also questionable is running back C.J. Prosise, who has missed three of the past four games with an ankle injury.

"He looked really good today," Carroll said. "We really checked him out today. We'll see how he feels tomorrow and all the way up to game day as well, but he looked to be at full speed. We need to see if he can recover from it and be OK, then make a call. With the game coming up on Thursday, we've just go to make sure we're right on this one."

Carroll said Jeremy Lane, who is listed as questionable with a thigh contusion, won't play "unless he can surprise us on Sunday. He wasn't able to work this week yet."

In addition to injury updates, Carroll provided an update on newly-acquired left tackle Duane Brown, who made a very quick adjustment in his first week of practice with his new team.

"He has done exceptionally well," Carroll said. "Like we said earlier, the carryover that he had from six years being in the same system has really ensured that he can make this transition as fast as you possibly could make it. He looks good, he has had good work, he got a lot of reps, and they really have fitted together well and are communicating well at this point, so we have every reason to think he's going to be able to play good football."

Washington, meanwhile, continues to be one of the most beat up teams in the league, with four players ruled out, including three starters, tight end Jordan Reed, left guard Shawn Lauvao and defensive end Matt Ioannidis. Three more players are doubtful, including Pro Bowl left tackle Trent Williams and starting center Spencer Long, and six players are questionable.
