Ticket demand for this weekend’s Las Vegas fight between Floyd Mayweather fights Conor McGregor continues to flag according to aggregator TicketIQ.

The cheapest ticket from the TicketIQ app is now available at $1,500 – down 35 per cent since the start of last week. The biggest price drop came on Thursday, shortly after the announcement that the fight would be taking place with both men wearing 8oz gloves.

The fight, which will take place at the 20,000-capacity T-Mobile Arena on the Las Vegas Strip, is yet to sell out despite predictions that tickets would be snapped up immediately.

According to the Independent newspaper, prices have dropped steadily over the past week, with the promoters of the fight eager to ensure that there are no empty seats come August 26.

Promoters seem unhappy discussing they have been surprised by the lack of demand.

“I’m actually tired of hearing that question,” the chief executive of Mayweather Promotions, Leonard Ellerbe, snapped at Mayweather’s open workout last week. “Right now, we have over 60 million dollars in the box office. What part of that remotely looks like ticket sales are slow?

“This isn’t a damn Rolling Stones concert. That’s the only thing that sells out in seconds. We’re talking about tickets that go from $500 to $10,000. That’s an expensive ticket.”

TicketIQ recently said it expects Mayweather vs McGregor to be the second most expensive combat sports event, behind only the Mayweather vs Manny Pacquiao fight in May 2015.
