Floyd Mayweather Jr, victor of Sunday's boxing match against Conor McGregor, allegedly tried to place a bet on himself.
According to ESPN, Mayweather entered an M Casino in Las Vegas, the day before to place a $400,000 bet that he would win.
Talk about confidence.
ESPN states that multiple sources have confirmed to them at around 3.30pm Mayweather bet on ending the fight in under 9.5 rounds.
The odds were -200.
While fighters are allowed to bet on their own straight win, the legality of anything other than that is too open to manipulation and a legal grey area.
When this bet was delayed, Mayweather reportedly tried to bet he would win by a knockout but eventually gave up due to the wait.
He was p***ed.
One source told ESPN.
Maybe he channelled that queuing frustration into the fight. If so, it worked.
McGregor was defeated one minute and five seconds into the 10th round, meaning Mayweather would have won big if either of his bets had been allowed.
After the fight Mayweather confirmed that he had tried to place the bet, telling ESPN:
I think that we bet 100 on 9½, I gave my guy six figures to go bet.
I have to make sure he bet because earlier today I went to the sports book to bet and they wouldn't let me bet.
According to Mayweather his friend was only allowed to place a bet for $87,000.
