vs
Vancouver Whitecaps (9-15-9) 36pts, 9th place Western Conference
At stake: The Cascadia Cup
It all comes down to this: a victory by 3 goals for the Caps gives them the Cascadia Cup. Any other result sees the Cup make the trip to Portland for the first time since 2012. A Portland win clinches a playoff spot in the Audi MLS Cup Playoffs. A draw or loss means things get confusing as their fate will be determined by what Seattle and Sporting KC do in their respective matches.
Here's what we know for sure:
Portland will be without Diego Chara (defensive mid) and Liam Ridgewell (centreback) because of yellow card accumulation.
