Floyd Mayweather, Jr. will make a guaranteed $41.5 million for the WBA/WBC junior middleweight unification fight against Saul "Canelo" Alvarez on Sept. 14, reports ESPN.com.

He made $32 million each for his May 2012 victory over Miguel Cotto and for his May bout against Robert Guerrero. In 2013, Mayweather will make an estimated $73.5 million.

"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," Mayweather adviser Leonard Ellerbe told ESPN.com. "It's a truly blessing to be in that position to make that kind of money. Floyd has worked hard to put himself in this position. He deserves every penny of it. He's the only athlete that has dominated his sport for the last 15 years and now he is fighting the best guy he can possibly fight."
