RENTON Seattle Seahawks Hoodie , Wash. (AP) — s proven more valuable this season than safety Bradley McDougald.And just in time for a visit from the leading passer in the NFL, the Seahawks aren't sure if McDougald will be able to play Sunday against Kansas City.McDougald's knee injury is one of several that could change Seattle's lineup for a Week 16 matchup where a victory and some help from others could clinch an NFC wild-card berth for the Seahawks. McDougald has been dealing with a patellar tendon injury that flared up during the first half last week against San Francisco and forced him to become a spectator for the vast majority of the loss to the 49ers. Seattle coach Pete Carroll said McDougald is away from the team for a few days getting additional treatment on his knee and is expected back by the end of the week.But when asked if he thought McDougald would be able to play against Patrick Mahomes and the NFL's top passing offense, Carroll could only say, "possibly." If McDougald can't play against the Chiefs it would be second-year safety Delano Hill stepping in. Hill played 52 snaps last week against San Francisco.Seattle is equally unsettled at right guard and potentially with its depth in the backfield.The Seahawks placed guard Jordan Simmons on injured reserve Tuesday due to a knee injury suffered in the loss to San Francisco and it's uncertain whether D.J. Fluker's injured hamstring will be healthy enough for him to return this week.The injuries have left Seattle possibly needing a major shuffle on an offensive line that has helped create the top rushing offense in the NFL.Ethan Pocic struggled last week when he stepped in for Simmons. Seattle has used George Fant as an extra offensive lineman for significant snaps throughout the season and his ability to play tackle could allow some shuffling among the starters in the short-term until Fluker can return."Let's wait and see on that one. We'll wait and see how this goes," Carroll said. "Jordan, he needs likely to get some work done on his knee to get him back so he's out. There are some decisions that we're making. Let's see how the week goes."Seattle signed running back Bo Scarbrough off the Jacksonville practice squad to take Simmons' roster spot and that's partly due to depth concerns at running back. Seattle played last week without rookie first-round pick Rashaad Penny due to a knee injury and Carroll said there was enough wear on starter Chris Carson and backup Mike Davis that they needed the extra depth in case Penny isn't back this week."It's uncertain if he can get back. We don't know that," Carroll said. "He's really determined to try and make it back and Friday is the day he can try to go for it and show that he can run and go for it."Amid all the injury news, the Seahawks believe veteran linebacker K.J. Wright will be back after missing the past five games. Wright hasn't played since Week 10 after aggravating a knee problem that first popped up in the preseason and required surgery.Wright said when he returned in Week 8 against Detroit that he took on too much and that eventually led to a setback. When he returns this time, he said he's going to be smarter about his play count and ramp up toward being ready for a full load when the postseason arrives — assuming Seattle gets there."We're going to be smarter this time. We've got a good game plan going," Wright said. "Ease it in these last two games Marshawn Lynch Color Rush Jersey , make the playoffs and kick it off from there." RENTON, Wash. (AP) — Of all the records the Seattle Seahawks have accomplished during Pete Carroll's tenure, he may not be more proud than what they can accomplish this week.The Seahawks enter Week 17 having committed just 10 turnovers all season, with five of those coming in the first two weeks in losses to Denver and Chicago. If Seattle can make it through the regular-season finale against Arizona without committing a turnover, it would join the 2010 New England Patriots and 2011 San Francisco 49ers as having the fewest turnovers in a 16-game season.It might seem like a somewhat obscure accomplishment. But for someone who preaches importance of securing the football the way Carroll does, it's a huge deal for the Seahawks. Seattle's low in turnovers for a full season under Carroll was 14 in 2014. "It's the No. 1 thing that we emphasize and we've been doing it for a long time," Carroll said on Wednesday. "What our challenge is, is how well can we emphasize it? And how well can we transfer than emphasis so they adopt that as part of their play? The mentality of it; there is a constancy that just goes away if you don't. You have to be on it because there are unnatural aspects of it when you play the things that you have to do. You have to train and drill with the highest of expectations to get it done."Seattle being in this position only highlighted the remarkable turnaround since the start of the season and coincided with an emphasis on being a run-first team that started with Week 3 against Dallas.The Seahawks turned around their 0-2 start and five turnovers in those two games and have gone 9-4 over the past 13 games while committing just five turnovers during that time.Seattle didn't commit a turnover in three straight games beginning in Week 3 and for the past five games the only turnover committed was a poor decision by Russell Wilson late in the first half against Minnesota when he tried to make a desperation pass attempt rather than throwing the ball away.That doesn't mean there haven't been close calls, such as last Sunday when Tyler Lockett fumbled a punt only to have it recovered by teammate Tre Flowers. Seattle has fumbled 18 times on the season and lost only four. But the major turnover issues have been completely avoided thus far."That's the No. 1 thing (Carroll) talks about every day," running back Chris Carson said. "When we break meetings, that's the last thing he says. Before practice that's the first thing he says. It's definitely the most important thing."Carson is responsible for a couple of those turnovers in the midst of running for more than 1 Germain Ifedi Color Rush Jersey ,000 yards this season. Carson lost fumbles in Week 1 against Denver when Seattle was still trying to figure out its identity, and Week 11 against Green Bay.The situation against Green Bay was a learning lesson and sign of trust for Carson. He fumbled on the first offensive play of the game and watched Green Bay convert the turnover into a touchdown.But on Seattle's next possession, Carson got the first carry. It only went for 2 yards but was still important."It just means that they trust in me and gives me the confidence I need," Carson said. "I know that when that happened I need to be more cautious the next time I'm out there."NOTES: Carroll said guard J.R. Sweezy was having additional tests on Wednesday about the extent of his sprained foot suffered against Kansas City. Sweezy was hurt midway through the second quarter. He was replaced by D.J. Fluker, who was only expected to play minimal snaps while recovering from a hamstring injury and ended up in for 61 percent of the offensive snaps. Fluker will be limited in practice this week. … Carroll said S Tedric Thompson (chest) and RT Germain Ifedi (groin) would practice on Wednesday after both missed last Sunday's win over Kansas City. … Carroll said he had not had much contact with Jody Allen, sister of former Seahawks owner Paul Allen, prior to the contract extension he signed with the team on Monday. "We have not hung out at all over the time, and we had one really significant meeting and a couple of phone talks and she's been really excited and really fired up about doing this," Carroll said. "Anybody who is a '12' that cares about the Seahawks should be really fired up about how she's looking at this and how she wants to go about it. She has a great love and spirit about the area and the club," he said.
