AUSTIN (KXAN) — This Sunday, two Texas MLS teams will face each other at Q2 Stadium in the Western Conference Semifinals, part of this year’s MLS Cup Playoffs — and single-match tickets sold out “instantly” Tuesday, according to the communications and media coordinator for Austin FC.

Austin FC and FC Dallas will kick off on that field at 7 p.m. on Oct. 23. The match will be televised on ESPN and ESPN Deportes.

Those wanting to experience it in person got the chance to snag tickets starting Tuesday at 10 a.m. People can still buy tickets through SeatGeek, Austin FC said. Interest was also high for the first round match, which Austin FC said sold out within minutes even before people knew when it would happen or who the team would play.

Austin FC defeated Real Salt Lake Sunday 3-1 in a penalty shootout after a 2-2 score at the end of extra time. Brad Stuver saved penalty kicks from RSL’s Andrew Brody and Braian Ojeda to help put Verde in the conference semifinals

This makes Austin FC the first team in MLS history to win four matches in a season where it trailed by multiple goals. It also has the longest-active home sellout streak in the league, with last week’s game marking 35 in a row, the team said. Austin FC has sold out 100% of its matches since it started last year.

The winner of this Sunday’s match will advance to the Western Conference Final set for Oct. 30.
