The famous clause that tore apart the negotiations to make a fight between Floyd Mayweather Jr. and Manny Pacquiao - will once again come up as Golden Boy Promotions will attempt to finalize a deal for Mayweather to fight Shane Mosley. Mayweather will demand random blood and urine tests for all of his future fights, according to Mayweather Promotions CEO Leonard Ellerbe.

Mayweather and Pacquiao were never able to reach a deal because the two fighters could not agree on the cut-off date for the random tests to detect performance enhancing drugs. During the BALCO scandal, Mosley admitted to taking performance enhancing drugs, inadvertently, before the 2003 rematch with Oscar De La Hoya. Mosley has never tested positive for any illegal drugs.

“Whoever fights Floyd Mayweather in the future, that person will be subjected to random blood and urine testing,” Ellerbe said to The Grand Rapids Press. “I don’t care who he fights, that will be the case. Floyd is out front, championing this effort to change the way the sport is handled in the future.”
