The Tuesday match will begin at 7 p.m. at the Starfire Sports Complex in Tukwila.
Those who cannot attend the match can catch it on SoundersFC.com as a live Webcast. The winner of the match will face the winner of the D.C. United-USL-1 Rochester match on Sept. 1 or Sept 2.
So Sounders FC fans, should this game be on TV? Should one of the local cable networks -- FSN or Comcast -- or even KONG/6 pick up this game? Does this U.S. Open Cup game have the same importance to you as a MLS game?
