In the past few years, Floyd Mayweather has consistently been the highest-paid athlete in the world. That should continue in 2013 with his upcoming fight against Saul “Canelo” Alvarez.

On Sept. 14, Mayweather will earn $41.5 million, according to adviser Leonard Ellerbe and Golden Boy promoter Richard Schaefer. The purse is a new record for one fight. Mayweather held the previous high, making $32 million for his bout in May against Robert Guerrero and his 2012 fight with Miguel Cotto.

In 2012, Mayweather’s guaranteed purse and winnings amounted to $85 million, according to Forbes. Manny Pacquiao came in second on the list with $62 million, followed by Tiger Woods and LeBron James.

"Floyd is the biggest star in the sport and the best in the sport, and when you're the biggest star and you are the best, you get paid the most money," Ellerbe told "So this comes along with the territory."

There’s a good chance the undefeated boxer will earn even more than the guaranteed $41.5 million. The Pay-Per-View could set a new mark for buys and revenue generated. In 2007, Mayweather and Oscar De La Hoya made history with 2.44 million PPV buys that drew more than $130 million.

ESPN reports that Alvarez is set to make north of $10 million. Both his and Mayweather’s contracts must still be filed with the Nevada State Athletic Commission.

Other than the boxers' earnings, more details have emerged about the Sept. 14 fight. The referee and officials for the bout have been chosen.

Kenny Bayless will oversee the fight. The veteran ref has worked a number of notable fights in the past, most recently the Pacquiao-Marquez IV bout. He has worked three bouts involving Mayweather, including his record-setting one with De La Hoya. It’s the first title fight Bayless has been assigned to in 2013, and it will be the first time he steps inside the ring with Alvarez.

Dave Moretti, C.J. Ross and Craig Metcalfe have been named as the judges as Alvarez tries to give Mayweather his first ever loss. Ross was involved in last year’s controversial fight that saw Timothy Bradley defeat Pacquiao in a split decision. She scored the fight 115-113 in favor of Bradley. Metcalfe is the one non-American judge.

Mayweather and Alvarez enter the fight with a combined record of 86-0-1. The bout is set to be a junior middleweight title unification fight.
