KIRKLAND, Wash. (AP) -Another week, another M*A*S*H-like stable of Seahawks injuries.

Leading receiver Darrell Jackson, plus starting offensive linemen Robbie Tobeck, Chris Gray and Floyd Womack, are all questionable for Seattle's NFC wild-card playoff game Saturday against the Dallas Cowboys.

Jackson was leading the NFL in touchdown receptions a month ago before he got his left foot caught in the turf Dec. 10 while an Arizona defender jumped on him. He missed Seattle's last three regular-season games, and did not even make the trip to his home state for last Sunday's win at Tampa Bay.

Jackson's biggest value lost, besides 10 touchdown receptions this season, is the unspoken understanding on improvisational pass routes he shares with quarterback Matt Hasselbeck. Jackson, a seventh-year veteran, hasn't practiced this week. But coach Mike Holmgren said he was ``holding out hope'' Jackson will play.

Holmgren was hoping Jackson could test the foot in practice Thursday. But after missing another practice Wednesday, Jackson said there likely won't be any tests until Saturday night.

``It's going to be a game-time decision whether I am going to play or not,'' Jackson said. ``But every day is looking brighter and brighter.

``It's getting better faster than I thought. I want to get out there a lot, to help this team start a tradition of getting into the big games, the NFC championship.''

The coach said receiver D.J. Hackett is ``in the same boat'' as Jackson. Hackett, who has 19 catches in his last four games after emerging when starter Bobby Engram was sick for two months, has a hip flexor. He is also questionable.

As for the offensive line, it remains as unsettled as it's been all through this uneven season. Seattle has used eight starting combinations among its interior blockers.

Tobeck, a 2005 Pro Bowl center, is back practicing - sort of. Tobeck worked some on Tuesday and then again Wednesday on the scout team. And the 13-year veteran struggled.

He lost 25 pounds after an abscess in his hip landed him in the hospital over Thanksgiving weekend. Tobeck said he's regained only 10 of those pounds.

``I was pretty dang sore today, which surprised me,'' said the 36-year-old who hasn't played since Nov. 6.

``I could tell I still don't have my legs with me. ... But coming from where I was four weeks ago, it's a lot of progress. Four weeks ago, I could barely lift 50 pounds without going home and taking a nap.''

Holmgren is waiting to see whether Gray or Womack can play before deciding whether Chris Spencer, Seattle's 2005 first-round pick as a center, or Tobeck will start at center. Spencer has started five games at left guard and the last eight at center.

Rookie Rob Sims is currently the left guard while Womack is rehabilitating a strained right groin. Veteran Tom Ashworth, signed last spring to be a tackle, would start for the first time this season at right guard if Gray doesn't recover from a badly bruised right thigh he's had for two weeks.

``The linemen will be game-time decisions,'' Holmgren said. ``Hopefully, they will be able to practice a little bit (Thursday). We'll see.''

The Seahawks list starting cornerback Marcus Trufant as doubtful, but Holmgren said Trufant ``obviously won't play'' Saturday. Seattle's best cover man sustained a high sprain of his right ankle in a Dec. 24 loss to San Diego.

``At this stage of the game, either you are in or you are out,'' Holmgren said. ``That was the speech I gave to them yesterday.''
