The Seahawks will host the New York Giants Sunday looking to build on the defensive momentum they have built over the past three games, but they may have to do so without a couple of key players on that side of the ball.

Starting right cornerback Tre Flowers is listed as doubtful, meaning he's unlikely to go, while defensive end Carlos Dunlap II, who has contributed four sacks in as many games with his new team, is questionable and will likely be a gameday decision according to Seahawks coach Pete Carroll.

"We'll find out about Carlos Dunlap here at the end of the week," Carroll said of Dunlap, who did not practice this week. "He was pretty bright-eyed about it today; we'll see what happens."

As for Flowers, the cornerback finished Monday's win, but his hamstring tightened up after the game. An MRI showed the injury isn't serious, but the turnaround off a Monday game means it's unlikely he'll make it back this weekend.  

"He came out of the game with his hamstring tight, did the MRI and he's got something that we have to deal with," Carroll said. "It's not a serious hamstring injury, but it's enough to really bother him this week, and to expect for him to turn around and bounce back around this week is a lot to expect. We'll see what happens. We'll take him all the way up to the weekend."

If Flowers can't go, Carroll said D.J. Reed will likely start in his place. Reed, who was claimed off waivers from San Francisco this summer, has already started at left cornerback, nickel corner, and returned kicks and punts, and now he has a chance to add right cornerback to his resume.

Also doubtful is right tackle Brandon Shell, who missed last week's game with an ankle injury. He is improving, Carroll said, just likely not fast enough to be ready for this weekend's game.

"Brandon kind of made a turn where he's really starting to move now," Carroll said. "It would be a surprised if he can play on this weekend, but he's getting real close. I would think he has really turned the corner to get well here."

Cedric Ogbuehi is expected to start again in Shell's place at right tackle.

Running back Carlos Hyde is listed as questionable with a toe injury, but both he and Chris Carson, who returned last week from a four-game absence, are good to go.

"We took care of those guys this week to make sure they'd both be ready to play," Carroll said. "We're counting on both of them."

Carroll also added that it's likely that Carson sees his workload increase after having only eight carries in his first game back from injury.

"More is good. I like seeing Chris play," Carroll said. "… It's likely that Chris will get the ball more than that."

In other running back news, Carroll said Rashaad Penny, who has been on the physically unable to perform list this season, will return to practice next week. The status of rookie defensive end Darrell Taylor, who has been on the non-football injury list all season, is less certain.

"Rashaad is practicing next week," Carroll said. "We're finally on it. We've made the commitment and we're doing it, so that that one is for sure. I have not heard back on Darrell's trip that he took. He left town to see some docs, so we'll find out about that."

Giants starting quarterback Daniel Jones is listed as doubtful with a hamstring injury, meaning the Seahawks will likely be seeing Colt McCoy at quarterback on Sunday.
