(Renton, WA)  --  The Seahawks close out the preseason on Thursday on the road against Marshawn Lynch and the Oakland Raiders.  Lynch will most likely not play along with most starters on both sides.  All NFL teams must trim their rosters from 90 players to 53 by Saturday afternoon.  Seattle is 3-and-0 in exhibition play thus far.  They open the regular season on September 10th at Green Bay.
