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."                       

The slip, which Vegas Stats & Information's Mitch Moss posted on Twitter, shows the bettor took Mayweather at minus-550: 

Purdum noted that while the slip says there's a payout of $120,000, the actual winnings would total $160,000. 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. 

Those numbers represent a significant shift from the opening odds in November that had Mayweather listed at minus-2250 and McGregor at plus-950.
