Did you know there was a Floyd Mayweather fight this weekend? You’re not the only one.

Not surprisingly, ticket sales are very slow for the Mayweather vs Andre Berto match next Saturday.

Chances are good that Mayweather and Berto will be fighting in an empty arena.

Apparently most of Mayweather’s fair-weather fans abandoned him after his last fight vs Manny Pacquaio in May turned out to be a dud.

Boxing fans don’t seem to care that this will be Mayweather’s “last fight ever.”

According to the Big Lead, only 25 seats were sold for the $1,000 and up tickets on StubHub.

With a little more than four days until Mayweather’s fight against Andre Berto at the MGM Garden Arena in Las Vegas, Ticketmaster shows there are more than 2,100 seats available — and that doesn’t even count the tickets that are typically held by the promoters.

StubHub spokesman Glenn Lehrman said the leading resale site had an average ticket sale price of $5,095 for Mayweather’s fight against Pacquiao, while the average sale for Saturday’s fight is more than six times less ($799).

At $125 for the nosebleed section, the cheapest tickets are still pretty steep.
