Pound-for-pound king Floyd Mayweather Jr. and junior middleweight champion Saul "Canelo" Alvarez signed on Wednesday night to fight Sept. 14 in the main event of a Showtime pay-per-view event at the MGM Grand in Las Vegas in the biggest fight boxing has to offer.
"I chose my opponent for September 14th and it's Canelo Alvarez," Mayweather tweeted to break the news. "I'm giving the fans what they want."
“It's been talked about for a while now, and now that it's signed, sealed and delivered, I am very happy. I will be the first to beat Floyd. ” -- Canelo AlvarezMayweather holds a world title at welterweight (147 pounds), but he also still owns a junior middleweight title (154), which he won by outpointing Miguel Cotto in May 2012. After that fight, Mayweather returned to welterweight and defended the title against Roberto Guerrero in a lopsided unanimous decision win on May 4 at the MGM Grand.
But he is moving back up in weight to face Alvarez (42-0-1, 30 KOs) with their belts on the line, although the fight will be contested at a catchweight of 152 pounds. On paper, Alvarez could be, literally, Mayweather's biggest test ever.
