(Carson, CA)  --  The Seahawks are on the road tomorrow as they take on the Chargers in preseason play.  The Hawks are 1-and-1 in exhibition play after falling to the Vikings 25-19 last Sunday.  Rookie receiver DK Metcalf is listed as 'doubtful' but will likely not play as he's headed for knee surgery.  Head coach Pete Carroll expressed optimism that the rising star won't be sidelined for long.
