From Sando:

Sean Locklear's one-game suspension means Tom Ashworth will start at right tackle Sunday against the Chiefs, coach Mike Holmgren announced today. Ashworth is much more comfortable at tackle than guard. He is more comfortable at right tackle than left tackle. This is clear from watching him practice, and this is also what Holmgren told us a few minutes ago. It's a tough spot for this team given that Floyd Womack is also unavailable, but at least Ashworth has considerable starting experience.

Hopefully Ashworth does well. Maybe he does well enough that the Seahawks Move Locklear to his natrual position at LG.
