The Seahawks just announced they signed free agent receiver Ruvell Martin from Green Bay.  Seattle just signed NE Patriot tight end Chris Baker to back up starter John Carlson, so I have no idea where Martin will play, but he surely will not see much time at tight end.  Martin seemed lost in the depth chart at Green Bay, but maybe the new GM in Seattle, John Schneider, formerly of Green Bay, sees something in Martin that must have escaped his former boss at Green Bay.
