PORTLAND -- On a day normally reserved for American football, football of the other sort will take a national stage Saturday with a rivalry match between the Seattle Sounders and the Portland Timbers.
The NBC-televised game gives a wide audience a taste of soccer in the Pacific Northwest, with its fervent supporters' groups, the songs and chants, and the choreographed fan "tifo" displays in the stands.
And of course there's the match.
Many who happen across the broadcast may not be aware of the game's implications to the teams involved. The outcome could determine the winner of the Cascadia Cup, the annual head-to-head competition between the Sounders, the Timbers and the Vancouver Whitecaps.
It could also send Seattle to the Major League Soccer playoffs.
