Mayweather-McGregor tickets have been a tough sell so far

Well well well...The fight that is being sold as a 'once in a lifetime event' doesn't seem to be having the kind demand promoters were probably hoping for early on. Tickets for Mayweather-McGregor have officially been on sale for five days now, and there are still hundreds of tickets available through Ticketmaster alone.

And these aren't just one-off seats either, ESPN has been doing some research and say fans can still purchase six seats next to each other in 162 different spots throughout the arena. That would cost a pretty penny though, which probably outlines the underlining issue with the event.

The cheapest tickets available on Ticketmaster are a cool $3,500 per seat, which doesn't include additional buyers fees of several hundred more and hotel accommodations and the like.

A ticketing expert at Temple University, Joris Drayer, says that fans are looking at shelling out roughly $10,000 for the event when taking into account flights and hotels on top of the price of admission.

"This is the challenge when pricing a one-of-a-kind type of event. No one knows what the demand will be," Drayer said in an email. "In this case, it seems the promoters overestimated what people would be willing to pay -- and how many of those people willing (to) pay thousands would actually attend the event."

The resale market on websites like SeatGeek and StubHub haven't been too hot either, with some suggesting that the high price of tickets have resellers wary of making purchases as it could be difficult to flip the tickets for a profit.

"There's fairly little sales going on in general," said Chris Leyden, a content analyst for SeatGeek.com. "I think a lot of it has to do with where prices are now. I think people are a little uncomfortable paying this much or maybe even more."

Seats near the ring are priced at roughly $10,000 apiece and there are also "platinum" seats available for up to $14,995. This is not exactly in the price range for your average fight fan.

But despite the news, promoters involved in the event aren't publicly expressing any concern (which is to be expected) and say they're still confident that Mayweather-McGregor will break all revenue records.
