Based on what I read, this fight is selling good to the fans, with this pandemic, its sales are pretty much affected and I don't think at this time they are buying for this, of course no, they are buying for the basic needs.
I also don't know if they have a target sales for this fight as its really affected significantly, less sales would make the promoter loss on their investment on this fight, so when this situation will be neutralize it's possible it will be postpone to give more time on the ticket sales and maybe PPV if there is.
Ticket sales will be affected but PPV sales will be higher than expected people will want to see the fight in their homes than watching it live, but I doubt if this fight will push through, I don't see this fight going to happen while the world is canceling all the big sporting events, they will definitely announce this soon and by the way surprise that in the poll Casimero is getting a lot of support.
