Share !(SportsNetwork.com) - Floyd Mayweather Jr. has been stripped of the welterweight world title he won after beating Manny Pacquiao this year for failing to comply with rules, the World Boxing Organization said on Monday. Mayweather, who improved to 48-0 by beating Pacquiao, let come and go the 4:30 p.m. ET Friday deadline by which he had to pay a $200,000 sanctioning fee from the May 2 fight (for which he earned more than $220 million) and vacate the two junior middleweight titles he also holds. It is against sanctioning organization rules for boxers to hold world titles in multiple weight classes. The WBC and WBA had been breaking their own rules by allowing Mayweather to hold their titles, but the WBO upheld its rules. "The WBO World Championship Committee is allowed no other alternative but to cease to recognize Mr. Floyd Mayweather, Jr. as the WBO Welterweight Champion of the World and vacate his title, for failing to comply with our WBO Regulations of World Championship Contests," the organization said in a statement. "The WBO has the utmost respect for Floyd Mayweather Jr. and all that he has accomplished during his storied career, and that Mr. Mayweather has always agreed with and understood that World Championships have both privileges and responsibilities and that status as WBO Champion is subject to and conditioned on compliance with the WBO rules and regulations." Mayweather originally planned to not accept the title as part of his post- fight pledge to vacate all his titles so younger boxers could have a chance at the belts. But when he did accept the WBO prize, he was required to pay the fee by last Friday in order to keep the title. Mayweather may appeal to the Complaint and Grievance Committee within 14 days. Meanwhile, WBO interim welterweight champion Timothy Bradley will now regain the full WBO championship.
