Floyd Mayweather claims the row over blood testing which is threatening his planned meeting with Manny Pacquiao is evidence the Filipino does not want the fight.
Pacquiao has refused to submit to blood testing in the 30 days leading up to the fight, which had been scheduled for March 13 but is now in doubt.
The Mayweather camp have insisted on both fighters making themselves available for testing, in accordance with US Anti Doping Agency regulations.
And they tonight issued a statement suggesting the Pacquiao camp does not “fully understand” the benefits of blood testing.
The statement from Mayweather Promotions and Golden Boy Promotions read: “Let the record be clear; Manny Pacquiao and his promoter Bob Arum are threatening to walk away from the largest fight in history.
“It is disappointing for us to see that the benefits of blood testing, and the fact that many different substances and procedures can only be detected by blood testing, are still not fully understood by all.
“Their ’take it or leave it’ approach, where blood testing would stop 30 days prior to the fight unless the Nevada State Athletic Commission (NSAC) approved differently, is another indication that they may not want this fight.”
On Boxing Day Pacquiao promised to take legal action over the row, saying he has had people asking “if I really take performance-enhancing drugs and I have cheated my way into becoming the number one boxer in the world.”
The Mayweather camp’s statement appeared to try to diffuse that issue, however.
It added: “Let it be very clear that nobody from Team Mayweather or Golden Boy Promotions is accusing Pacquiao of anything.
“But the reality seems to be that, for whatever reason, Pacquiao does not want to participate in random blood testing, which has already been deemed a harmless procedure that many current athletes are subjected to, prior to and during competition.”
The statement also claimed Pacquiao had blood taken 14 days before his fight with Ricky Hatton in May, which the Filipino won with a second-round knockout.
“Also, when told that Pacquiao feels that the United States Anti-Doping Agency (USADA) is an agent of Golden Boy Promotions – which is in and of itself a ridiculous accusation – we moved swiftly and made yet another concession by stating that we would be perfectly fine to retain another agency which would do the random urine and blood tests and jointly agree on a reasonable cut-off prior to the fight, but which would still maintain the integrity of the results.
“Let it be clear that this procedure was declined by Pacquiao as was the proposal to bring in an independent mediator such as Senator John McCain, a suggestion that was in fact embraced by Bob Arum, but also declined by Manny Pacquiao.”
