On Friday, an anonymous bettor in Las Vegas placed an $880,000 wager on Floyd Mayweather Jr. to defeat Conor McGregor when they duke it out Aug. 26 at T-Mobile Arena.
According to ESPN.com's David Purdum, the bet "is believed to be the largest placed on the fight in Las Vegas at this point."
That's because South Point Casino's computer system doesn't print slips with payouts over $1 million.
As a workaround, South Point reportedly decided to print up a pair of $440,000 slips for the anonymous bettor.
As of Friday, Mayweather remained a minus-550 favorite with McGregor penciled in as a plus-375 underdog.
