--QB Matt Hasselbeck, still restricted by his back injury, will serve as the team's third quarterback this week.

--LB D.D. Lewis did not practice Wednesday because of a shin injury and will not play on Sunday.

--LB Leroy Hill did not practice Wednesday because of a shoulder stinger and will not play on Sunday.

--S Jordan Babineaux practiced on Wednesday and will be able to play Sunday against Arizona.

--DE Brandon Miller did not practice Wednesday because of a wrist injury and is questionable for Sunday's game.

--K Brandon Coutu did not practice on Wednesday because of a groin injury. He has not played all season.

GAME PLAN: The Seahawks must slow Arizona's receiving tandem of Larry Fitzgerald and Anquan Boldin, who combined for 23 catches and 337 yards. Seattle is likely to pressure Kurt Warner from the very start this game rather than sitting back in a zone.

MATCHUPS TO WATCH: Seahawks CB Josh Wilson vs. Cardinals WR Anquan Boldin - Wilson was named the NFC Defensive Player of the Week after his two interceptions against the Jets. Boldin is likely to get thrown to early and often since Marcus Trufant is likely to stick with Larry Fitzgerald.

--Seahawks RB Maurice Morris vs. Cardinals run defense: Morris is coming off a 116-yard, 29-carry effort. Arizona ranks 17th against the run. If Morris can keep the ball out of Cardinal QB Kurt Warner's hands, the Seahawks stand a far better chance of winning.

INJURY IMPACT: Neither linebacker Leroy Hill nor D.D. Lewis will be able to play this week because of injuries, which means that Will Herring once again will get the start, as he did last week against New York. Also, safety Jordan Babineaux is back from a concussion, which kept him out against the Jets. Babineaux is the team's dime back, a spot that was filled by Kevin Hobbs last week.
