RENTON, Wash. — The Seattle Seahawks will be without quarterback Matt Hasselbeck for at least one more game because a bulging disk in his back is causing problems with his knee.

Coach Mike Holmgren says Hasselbeck will not play Sunday night when the Seahawks are at Tampa Bay. Hasselbeck sat out Sunday's 27-17 loss to Green Bay.

Holmgren says Hasselbeck saw a specialist in Los Angeles, who determined the disk problem in his back was causing the quarterback weakness in his right knee. Hasselbeck hyperextended his right knee in Seattle's loss to the New York Giants on Oct. 5.
