By GREGG BELL AP Sports Writer RENTON, Wash. (AP) - Matt Hasselbeck fully participated in a practice for the first time since his back stiffened 10 days ago. The Pro Bowl quarterback says he will play in the Seahawks' next preseason game Aug. 25 at San Diego. Coach Mike Holmgren says starting right tackle Sean Locklear is out at least two weeks and could miss the Seahawks' opener because of a sprained knee. Holmgren said Monday he was hopeful Locklear would be back for the opener Sept. 7 at Buffalo but that it would be close. Locklear is wearing a bulky knee brace over a sprained ligament in his left knee. The three-year starter got hurt early in Saturday night's preseason win over Chicago. Starting center Chris Spencer (back) practiced for the first time this preseason but was held out of team drills.
