The Seahawks are getting a key piece of their defense back for their wild-card game against the Eagles, with free safety Quandre Diggs set to make his return after missing the previous two games with an ankle injury.

"He had a good week," Seahawks coach Pete Carroll said. "He really was able to go right back in on Wednesday and take the reps and finished up looking just like he was fine. That's really a good deal, a real plus for us. He's had real positive impact on us, and hopefully he can do that again."

Diggs, who came to Seattle in a midseason trade with the Lions, will be making his playoff debut—he was injured the one time Detroit reached the postseason while he was there—and the Seahawks hope he can have the same kind of impact that he did in five regular season starts when he had four takeaways—three interceptions, one of which he returned for a touchdown, and a forced fumble against the Eagles that he was also able to recover.

Also set to play this weekend is defensive end Jadeveon Clowney, who was unable to practice Wednesday or Thursday as he continues to manage a core injury that he has been dealing with since Week 10.

"We're just getting him to game time is all we can get done right now," Carroll said. "He worked today, he got his reps in today and was able to demonstrate the game plan that he knew what was going on and all that. So if this what we've got, this is what we've got. We've got to work with that."

The Seahawks have three players ruled out: tackle Duane Brown, who had knee surgery after Seattle's Week 16 game against Arizona, receiver Malik Turner, who will miss a second straight game having not yet cleared the concussion protocol, and linebacker Mychal Kendricks, who tore his ACL last week, but has not yet been placed on injured reserve.

Two players are questionable, guard Mike Iupati, who is dealing with a stinger, and receiver Jaron Brown, who injured his knee last week.

On Iupati, Carroll said, "We've got to wait and see. We'll go all the way to game time."

Jaron Brown's designation as questionable comes as a surprise considering Carroll said on Monday that the veteran receiver would not be able to play this week. Brown was away from the team Friday tending to a family matter, but would have been able to practice had he been in attendance.

"Really, I was just telling you what we thought," Carroll said of prematurely ruling Brown out. "He jumped back, did some stuff on Wednesday feeling pretty good, did a little bit on Thursday. He would have practice today; he had a family thing he had to take care of, so he had to head out of town here. So I don't know what to tell you about game time with that. He's got to take care of his family thing first, but we anticipated that today he was going to practice and go, and we were shocked—he just bounced right back from it. I can't explain why other than that it's just a good thing for him and the club if he's able to play."

On Duane Brown, who was holding out a little bit of hope that he could play early in the week despite being only two weeks removed from surgery, Carroll said, "He won't be able to jump right back. He's still feeling the effects of the surgery. The challenge is to get rid of the swelling. He's not bad, but he's working through that. He wasn't able to make it this week. There was a chance—this would have been crazy if he'd have come back out—so we'll see where he is next week."

The Seahawks will get back tight end Luke Willson after he missed last week's game with a hip injury.

"It really helps us to get him back," Carroll said. "His experience—he does a number of things and he does them well, at the line of scrimmage, on the move, routes, all kinds of things. We have such background with him. It's really valuable."

Not on the injury report this week was running back Marshawn Lynch, who bounced back surprisingly well from his first game action in 14 months.

"He had a really good week," Carroll said. "Seemed like it was smooth for him all the way throughout. He felt really good all the way through the practices, took all the reps that he needed to take. I was a little surprised at that. I thought maybe it would take more of toll in the first game, but it didn't, so we're in good shape going in. it really does feel different than it was a week ago at this time, because we didn't know what was going to happen. We feel confident that we have a real nice mix in our style of runs from our guys. So it's a different feeling. We're more confident that we know what we've got this time around."

For the Eagles, Pro-Bowl right tackle Lane Johnson is questionable with an ankle injury, and Pro-Bowl tight end Zach Ertz is questionable with rib and back injuries. Receiver Nelson Agholor is out with a knee injury.
