The war of words has ended with a challenge. On Wednesday, WBC welterweight champion Floyd Mayweather Jr. (43-0, 26KOs) lashed out at WBA/WBC super middleweight king Andre Ward (26-0, 14KOs). He took shots at Ward's ticket selling abilities. Ward's manager, James Prince, who used to manage Mayweather years ago, fired several verbal shots right back at Mayweather

But now Ward himself has come out in the public and challenged Mayweather to a catch-weight fight at 160-pounds. Mayweather has never fought higher than 154, but Ward is willing to drain his body to head eight pounds south. Mayweather defends his title against Ward's close friend, Robert Guerrero, on May 4th at the MGM Grand in Las Vegas.

Ward stated on the social networks - "Lil Floyd says he spars middleweights. He is the only man I will sacrifice coming to 160 for. He won't take that bait!!!"
