The Western Conference semifinals between Seattle and Vancouver moves to CenturyLink Field Thursday night after a nil-nil opening leg at B.C. Place on Sunday.
That result left the Sounders with a couple options to advance: 1) Win, or 2) Another shutout tie, which would force a shootout. Allow any Whitecaps goals, and the Sounders will have to win outright because of the MLS road-goals tiebreaker.
The Sounders finished with a draw in Vancouver, despite the absence of Clint Dempsey. The veteran attacker drew a red card in the regular-season finale, leaving him suspended for their playoff opener.
