Seattle's Marcus Tubbs will miss the 2007 season after tearing the ACL in his right knee Thursday night during the first quarter of the Seahawks' 19-14 victory over the Oakland Raiders in their preseason finale. The team offered no official word regarding Tubbs' injury Friday, but sources indicated that he will have season-ending surgery to repair the damaged ligament. The loss of the 320-pound Tubbs is a significant blow, since he was expected to help fortify a defense that ranked 22nd against the run last season and allowed an average of 4.6 yards per carry -- which tied for fifth highest in the league.
