LAS VEGAS (AP) - Floyd Mayweather will fight young Mexican star Canelo Alvarez on Sept. 14 at the MGM Grand.
``I chose my opponent for September 14th and it's Canelo Alvarez,'' Mayweather said Wednesday night on Twitter. ``I'm giving the fans what they want. It will be at the MGM Grand.''
Alvarez sent a tweet in Spanish announcing the fight.
The 36-year-old Mayweather is unbeaten in 44 fights, the last a unanimous 12-round decision over Robert Guerrero on May 4 at the MGM Grand in defense of his 147-pound title.
Alvarez is 42-0-1. The 22-year-old fighter unified the 154-pounds titles April 20 in San Antonio with a unanimous victory over Austin Trout.
The fight will be contested at 152 pounds and offers a rare bout between two unbeaten fighters in their primes.
``Floyd has said from Day 1 that he wants to give fans the best fight out there and here it is,'' Mayweather's co-manager, Leonard Ellerbe, told the AP. ``We have the two biggest stars in the sport and they're fighting each other Sept. 14.''
The bout will be the second in Mayweather's six-fight, 30-month contract with Showtime that could pay him more than $200 million.
