The New York Cosmos fans and supporters are bringing some healthy numbers to Red Bull Arena.

According to various sources, Cosmos fans have amassed a traveling contingent of just over 400 fans for their U.S. Open Cup encounter against the New York Red Bulls. It is an impressive number for the division two side, particularly for a midweek encounter. One source tells us seats in the visiting 220 section have all sold out, with some Cosmos fans taking seats in the adjoining sections at Red Bull Arena to join their contingent.

Overall, the crowd will be light in Harrison, though larger than most Open Cup encounters. Just over 10,000 fans are expected to be in attendance Wednesday night, with a light walk-up crowd expected. How tickets sold will translate to actual attendees, however, is anyone’s guess.

The New York Red Bulls earned their spot in the U.S. Open Cup Fifth Round after thrashing NASL minnows Atlanta Silverbacks in the fourth round of the tournament. The Cosmos, meanwhile, defeated both Jersey Express and New York City FC to earn their position in the competition.

Both teams faced during last year’s U.S. Open tournament, with the Cosmos beating the Red Bulls 3-0 at Hofstra’s Shuart Stadium.

The winner of this match goes on to play the Philadelphia Union at PPL park in the quarterfinals of the tournament.
