The boxing world stood in delight when both sides confirmed that Floyd Mayweather Jr. (44-0, 26KOs) will fight Mexican star Saul "Canelo" Alvarez (42-0-1, 26KOs) for the WBC/WBA junior middleweight titles on September 14th at the MGM Grand in Las Vegas.

The fight takes place at a catch-weight of 152-pounds, which is two pounds below the junior middleweight limit.

"Canelo can come in at 200-pounds if he wants to, he'll still get his butt whipped," Ellerbe told Steve Carp. "Floyd is the best athlete in sports. He won't have any problems with 152-pounds."

The bout will be the second in Mayweather's six-fight, 30-month contract with Showtime that could earn him more than $200 million.
