Utah and SL County government approved 26% capacity for MLS games at Rio Tinto - 5,300 allowed out of 20,000 capacity.
So, expect a similar 25%ish capacity at LES. Which means about 16K per game. Probably a 2K student section and the rest based on Cougar Club season ticket priority. Tickets to every home game will likely be only available to Legacy-level members.
I'm hoping they can get capacity over 20K, which could be possible if they allow some larger physical distancing groups of like 6-8 tickets together.
