RENTON, Wash. -- Matt Hasselbeck has returned to Los Angeles for a second visit to a back surgeon, and Seahawks coach Mike Holmgren says Seneca Wallace remains Seattle's starting quarterback for now.

Hasselbeck was having another evaluation on the bulging disk in his back, Holmgren said Monday. The disk is pushing on a nerve that is weakening the three-time Pro Bowler's hyperextended right knee.

Unless Hasselbeck passes a strength test so he can practice before Friday, he will miss his third consecutive game when Seattle (2-5) hosts Philadelphia (4-3) on Sunday. Holmgren reiterated Hasselbeck's status is week-to-week.

Holmgren said a quarterback has to have a strong week of practice to prepare for the array of blitzes the Eagles' defense uses.
