DT Marcus Tubbs landed on injured reserve today, ending his 2006 season. We alluded to increasing concerns about his knee in our report this morning. Tubbs has been sidelined on and off since the end of last season. The team filled the open roster spot by signing LB Lance Laury off the practice squad (Seattle announced this move a couple hours ago. I've been away from the computer until now).
With Laury coming onto the active roster, it's fair to wonder whether D.D. Lewis might be the next candidate for injured reserve. His toe injury looks like something that will linger. Lewis' situation explains why they would want Laury on the active roster. You have to wonder, too, what they would do if something happened to FB Mack Strong. Josh Parry has been the backup, but he could miss several weeks with a foot injury. Depth is running low at several positions.
They could always sign FB David Kirtman to the active roster down the road. This would be easier to do, in theory, once Shaun Alexander is back. A healthy Alexander negates the need to keep Marquis Weeks on the 53-man roster. Without Weeks, there would be a spot for Kirtman (assuming the team is worried about being one injury away from lining up without a fullback). Parry's situation would come into play there, too. They haven't said how long he'll be out, but he wasn't even "doubtful" for this game Sunday.
