After two weeks of Audi 2015 MLS Cup Playoff action, we have our matchups for the Conference Championships. The winners of these duels will meet in the MLS Cup on December 6.


The Eastern Conference Championshp features two teams who have been around since the start of the league in 1996: Columbus Crew SC is set to face the New York Red Bulls. The two teams have faced off more than 50 times in the MLS regular season, most famously in the 2008 MLS Cup.


A less-storied, but no-less-intriguing matchup takes place in the West, where the Portland Timbers and FC Dallas play each other in the playoffs for the first time after 13 regular-season matchups (5 years). And yet there already have been high-profile moments in this rivalry, including an incident involving a tissue earlier this season.


Below you can find a complete history of the two matchups, including an in-depth look at this year's games.
