MLS Playoffs: Sounders will face FC Dallas in conference semifinals

It took 120 minutes, plus 11 rounds of penalty kicks but the Seattle Sounders' Western Conference semifinal opponent is finally set. With the Portland Timbers' win over Sporting Kansas City on Thursday, that means the Sounders are the lowest remaining seed and will face FC Dallas. The first leg is scheduled for a 6:30 p.m. kickoff on Sunday. The match will be broadcast on FoxSports 1.

The Sounders faced FC Dallas twice this year, going 1-0-1. Early in the season, they played to a 0-0 draw in Texas despite the Sounders missing Clint Dempsey, Obafemi Martins, Osvaldo Alonso, Chad Marshall and Marco Pappa. It's entirely possible the Sounders' starting XI on Sunday could feature as few as four players who started in that earlier match.

The second meeting was on June 13 in Seattle, a match the Sounders won 3-0. All three of the Sounders' goals came in the second half. Martins came off the bench and Alonso was out for that one, as well.

While Dallas' lineup will likely be more similar to the ones they used in the previous matchups, it should be said that they went 12-5-2 after their loss to the Sounders and finished the season with 60 points, only to fall short of the Supporters' Shield on a tiebreaker.

This is also a rematch of last year's Western Conference semifinals, with the roles reversed. The then-top seeded Sounders won that matchup on the away-goals tiebreaker.
