Seattle quarterback Matt Hasselbeck returned from his appointment in California with back specialist Dr. Robert Watkins on Tuesday.
Hasselbeck said during his weekly interview on KIRO-AM radio that he did not pass a strength test given to him and will not be cleared to play this week.
This means Seneca Wallace will likely get the start at quarterback against Philadelphia.
"I thought they would clear me," Hasselbeck told KIRO. "He did not. And so I need to see him again real soon. I basically can't get cleared until I pass his test. And that's what I'm working towards."
Never miss a local story.
Specifically, Hasselbeck said he did not pass a test that required him to walk on his heels.
Hasselbeck would miss his fourth straight week if he can't play on Sunday.
Right now, Hasselbeck said he's suffering from a dead leg due to the bulging disk in his back. Hasselbeck did say Dr. Watkins told him the injury will not require surgery.
"It doesn't feel different necessarily," Hasselbeck told KIRO. "It's just that because of the disk issue in my back, that nerve is shutting off the muscles that are supposed to work in your leg. So that's what I'm working on and I'm confident it'll get better."
Hasselbeck's brother, Tim Hasselbeck, said on ESPN this afternoon that Matt Hasselbeck's injury might require him to sit out longer that the week-to-week prognosis announced by Seattle coach Mike Holmgren this week.
