Sporting KC will be out for revenge after Portland eliminated it from the U.S. Open Cup on Tuesday.
Portland won Tuesday's meeting 3-1, with two goals from Gaston Fernandez and a penalty converted by Will Johnson. The victory prevented the 2012 winners from continuing their bid to hold the Open Cup and MLS Cup at the same time.
Sixth-placed Portland has 20 points right now, and with the trio of Colorado, Dallas and Vancouver sitting just above with 22 each, a win would, temporarily at least, put the Timbers into possession of a postseason berth. With Colorado and Vancouver playing on Saturday, the opportunity is even more apparent.
Reigning MLS Cup champion Kansas City went into the World Cup break on a win, but it came at the end of a dismal 0-3-2 winless run, and KC is now three points behind Eastern Conference leader D.C. United.
What's more, Kansas City is missing a number of important players. Antonio Dovale is serving a suspension, while Matt Besler and Graham Zusi are on World Cup duty with the USA.
The match will give Timbers fans a first chance to see their team's newest signing, defender Liam Ridgewell, in action.
