Floyd Mayweather has been stripped of his WBO world welterweight title, according to multiple reports.

Mayweather won the WBO belt in his unanimous decision victory over Manny Pacquiao in May. However, the WBO took the title away Monday after Mayweather failed to pay the $200,000 sanctioning fee.

"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 WBO wrote in a statement to ESPN.

The 38-year-old Mayweather improved to 48-0 with his victory over Pacquiao, a fight that generated more than $600 million in pay-per-view and ticket revenue and paid Mayweather a reported $180 million. Mayweather remains champion in the WBC and WBA, in both the welterweight and super welterweight divisions.
