On Monday, the club stated that they would be selling tickets at the 400 level because of high demand. The announcement comes less than ten days after the club opened the 300 level.
Sunday's game will far surpass the expected normal capacity of 27,526 as the entire stadium will be open for fans.
"Demand for seats for this historic game has been tremendous and momentum is growing by the day," Club President Tom Glick said via a release. "Now with more than 30,000 sold, we have decided to open even more seats."
A number of Revolution fans will be present for this historic event as the Midnight Riders and The Rebellion have organized bus trips. While the deadline has passed to get on the Riders' bus, fans can still venture down with The Rebellion. Members of the group can get on the bus for $70 while non-members will pay $80. Both options include a game ticket and must be purchased by Wednesday, Mar. 11.
