(Seattle, WA)  --  The Seattle Seahawks are winners of two straight games, following a 39-30 defeat of the Pittsburgh Steelers.  Russell Wilson passed for a career-high five touchdowns in a game that saw seven lead changes.  However, there was bad news for Seattle, as tight end Jimmy Graham suffered a knee injury that will require surgery and keep him out for the rest of the season.  The Seahawks will visit Minnesota next Sunday.
