The Seahawks leave for Baltimore Friday ready to take on one of the league's top teams, the AFC North leading Baltimore Ravens.

"This is a really challenging matchup," Seahawks coach Pete Carroll said. "Even getting through the week, now we've done the plans in all phases here, it's still a really big challenge, because these guys are so good at everything. It's going to really call on us to be at our best, and that's a great thing. Hopefully we'll be able to pull this thing off and get a great win out there."

The good news for the Seahawks is that they're making this trip east with a pretty healthy squad, with only two players on the 53-man roster listed as questionable, guards Phil Haynes and Anthony Bradford, and none listed as doubtful or out. Also questionable are running back Kenny McIntosh and nose tackle Austin Faoliu, who both returned to practice from injured reserve but have not yet been added to the 53-man roster. 

"It certainly feels like that," Carroll said when asked about the team being healthier than it has been for a while. "This week there were so many guys on the practice field, guys fighting for reps, which was great. It's the first time we've felt like that in a long time. It would be like if you came off a bye or something like that, we feel like we got a big boost from the guys who are out there battling."

Among the players on the practice field this week, of course, was newly acquired defensive end Leonard Williams, who has made a good first impression since arriving in a trade earlier this week.

"He looked exactly like we had hoped," Carroll said. "He was great. Picked stuff up, no problem with him learning the scheme, the principles and all of that. Everything carried over, so he'll get a chance to play."

On Haynes, who has missed the last three games with a calf injury, Carroll said, "He worked well today. He was out there going, and (Damien Lewis) was out there going too."

Asked if Haynes would play, Carroll said, "We've got to see how this whole week hit him and see what we get from the docs. We don't know that yet."

On Bradford, who started the last three games at right guard in place of Haynes, Carroll said, "He couldn't do much today. We'll have to wait and see."

As for McIntosh and Faoliu, both practiced fully, but in order for them to play, the Seahawks would have to make a roster move by Saturday to add them to the 53-man roster. 

"They're both practicing and going, they look like they're right in the flow of it," Carroll said. "So we'll see how that goes, but again, that just continues to help us feel the depth, guys being healthy and out there working and taking reps, it's a good thing."

Carroll also said that Jason Peters will play again after making his Seahawks debut in last weekend's game. Peters, who is in his 20^thseason, split time at right tackle last week with Stone Forsythe, and Carroll said earlier in the week he wouldn't have a problem rotation at that position again. Peters will need to be elevated from the practice squad in order to play Sunday.

Receiver Jersey Swap

For reasons that as of now remain a mystery, receivers DK Metcalf and Tyler Lockett decided to switch jerseys during Friday's practice, creating an interesting visual given the size discrepancy of the two.

"They had a little switch on us with the jerseys today," Carroll said, before joking, "I couldn't tell one guy from the other. I was all screwed up."

Carroll described the two result of the swap by saying, "Tyler's jersey on DK looked like a bikini. I don't know how he's going to get it off. The other way around, you look at Tyler, it looks like he's wearing his big brother's jersey."

Big Man Flipping

During an otherwise routine pre-practice stretch Thursday, defensive end Mario Edwards Jr., who is listed at 6-foot-3, 280 pounds, just casually executed a smooth backflip, an impressive display of athleticism for an athlete of that size.

Carroll said he was unaware that the 29-year-old Edwards, who signed with the team this offseason, was capable of such a feat.

"I did not know that," Carroll said. "That shocked me yesterday when I saw that. I was going to show mine, but I thought, 'Nah, I'll hold off a little bit.' Didn't want to take away from his coming out with the back flip.

"He's a very big guy to do that. It was a shock to see that. Pretty cool."
