Oscar De La Hoya is not letting up on his criticism of the Floyd Mayweather Jr. vs. Conor McGregor fight, which he has for months bashed as an embarrassment to the sport. Following a promotional event for his upcoming Golden Boy Promotions match between Canelo Alvarez and GGG, the former Mayweather rival once again dismissed the cross-sport fight as "a fraud," and alleged that the event was such a money grab that the 50-0 great was literally trying to cash in up until the very last second.

"It was all a fraud. I just heard this morning that Mayweather tried to bet on himself in the tenth round. Um, and they uh, they turned him away. So, if that's no indication, then what is?" Mayweather told reporters on Monday, August 28.

While it isn't confirmed that there is any truth to him attempting to log a wager just before finishing the UFC champ off, Mayweather has indeed acknowledged that he bet on himself in the fight. In fact, he managed to find the time to sit down with Steve Levy and Stephen A. Smith during ESPN's post-fight coverage outside of T-Mobile Arena, and it was at that point that he divulged exactly how he bet, and how much he bet. "They didn't let me bet $400,000. Earlier today I went to go bet $400,000 and they didn't let me bet, uh, at a casino that I went to," Mayweather told Levy and Smith.

"They said I was a promoter and I guess they thought the fight was gonna be set up. I'm not going to set up a fight for $400,000 when I'm making over $300 million," said Floyd. He then went on to explain that he gave a friend the $400,000 to wager for him but said they only let him put up $87,000.
