The Pacquiao-Mayweather fight, supposedly the biggest boxing megafight ever, has been waived off by Top Rank Promoter Bob Arum over blood testing disputes. Arum himself declared the megafight between Manny Pacquiao and Floyd Mayweather Jr. dead, even though efforts had supposedly continued to find a compromise over the disputed blood testing mechanics.

Arum, perpetrator of the now dead Pacquiao-Mayweather fight, simply stated:

“It’s over. O-V-E-R.”

Manny Pacquiao VS. Floyd Mayweather is no more.

The only issue left to be resolved for the Manny Pacquiao VS. Floyd Mayweather boxing fight was the blood testing, said Arum, who had set a Thursday deadline for its agreement over it. But with the strong insistence of Floyd Mayweather,  Jr. and his camp over the use of the U.S. Anti-Doping Agency (USADA) to conduct the tests, Arum was left to put a damper on the biggest fight in boxing history. Arum stated over the USADA blood testing issue that derailed the Pacuquiao-Mayweather fight:

“They’re viewed by the Pacquiao side as being partisan. He doesn’t want to use them. I don’t want to use them. They’re so inflexible they can’t be used.”

Bob Arum had moved forward from the issue and has issued a fight for Manny Pacquiao against Paul Malignaggi, a speedy boxer who had been defeated before by Ricky Hatton. Hatton had been demolished by Pacquiao earlier in the year. Arum, however, stated that there was still a chance that Pacquiao and Mayweather could fight late 2010.

“As far as I’m concerned the fight is over. Can it be revisited in the fall? We’ll see.”

The blood testing issue is central to the troubled Pacquiao-Mayweather boxing megafight, due to the insistence of Team Mayweather to use Olympic-style drug testing for the fight, which will be administered by the USADA. This amidst the absence of any speculation of either Pacquiao or Mayweather of even being linked to any performance-enhancing drugs.

The USADA blood testing methodology is in start contrast with the Nevada regulations, which both Pacquiao and Mayweather had always been subjected to. Under the Nevada regulations, boxers are generally only tested just before the fight and in the dressing room afterward. Moreover, only urine is required, unlike under the USADA were several blood tests are needed. Pacquiao is quite apprehensive of needles and the fact that so much blood will be drained of him, which he fears will weaken his performance.

Though Manny Pacquiao has agreed to blood tests to a certain extent, the Filipino boxing hero does not want blood testing to be immediately done before the fight because he believes giving blood so soon before a fight will weaken him. USADA holds steadfast in its claim that all athletes should be subject to random and unannounced testing at any time. Kobe Bryant, Lebron James, and Michael Phelps were no exceptions; the same holds for the big Manny Pacquiao VS. Floyd Mayweather boxing fight.

The doomed Pacquiao-Mayweather fight, which was expected to be the richest ever, was set to award both boxers with approximately $30 million to $40 million.
