Only standing room tickets remain for Tuesday's first leg of the Eastern Conference Championship in Columbus.

Crew SC president Andy Loughnane told Columbus Dispatch reporter Andrew Erickson earlier this week that he expected MAPFRE Stadium to be sold out for the opening match of the series against Toronto FC (8 pm ET on ESPN, ESPN Deportes in US; TSN, TVAS in Canada).

The Houston Dynamo announced a sellout for the first leg of their Conference Championship series against the Seattle Sounders with more than a week to spare before the match, which will also be played on Tuesday (9:30 pm ET on FS1, FOX Deportes in US; TSN, TVAS in Canada).

Crew SC used the opening leg of their Eastern Conference Semifinal series to log a comprehensive 4-1 victory against New York City FC. That match, the first in Columbus following the news that owner Anthony Precourt was considering a potential move to Texas, gave Crew SC the edge they would need to advance in the aggregate-goal series despite a 2-0 loss in the second leg.
