TMZ: Floyd Mayweather vs. Andre Berto is on

But he lost to Victor Ortiz and Robert Guerrero, two “opponents” easily vanquished by Mayweather, and journeyman Jesus Soto Karass. But judging by his diet, he’s either supremely confident he’ll win, or he just doesn’t care.

In the sport of boxing, securing a bout against the PPV king Floyd Mayweather Jr., is an equivalent of winning the lottery.

Undefeated pound-for-pound champion Floyd Mayweather Jr. has announced that his opponent for his upcoming September 12 fight will be former IBF and WBC welterweight champion Andre Berto.

A source close to Berto said that Berto (30-3, 23 knockouts) hasn’t been officially notified he will fight Mayweather next. If the report is true, it may confirm a popular theory about how Mayweather wants to end his career – with an easy opponent that will let him retire undefeated.

Mayweather is coming off a unanimous decision victory over Manny Pacquiao in the so-called “Fight of the Century” last May 2. Mayweather’s farewell fight may prove an effective way to put an exclamation point on those efforts.

Even though Mayweather himself raised the possibility that he might fight Berto on September 12, the suggestion was not widely taken seriously in June.

“It’s a pleasure and honor to be in this position and I’m looking forward to capitalizing on every moment of it”, Berto told TMZ Sports. Right now, the biggest question is how much revenue the fight would get from advertisers once it is aired on CBS. Granted, the title he won from Pacquiao became null-and-void because fighters can’t have titles in more than one weight class, but he still beat the pac-man nonetheless.

“I just don’t see how he fights on pay-per-view after everyone’s talking about him fighting on free TV”, said an industry source.

Mayweather is regarded as the world’s highest-paid athlete, cumulatively earning $420 million in his boxing career.

It’s true that Floyd Mayweather couldn’t care less about what you think when it comes to his career choices.
