Travis Tygart, chief executive of the United States Anti-Doping Agency (USADA), has weighed in on the recent controversy over a proposed $5 million dollar fine if Floyd Mayweather Jr. or Manny Pacquiao tested positive for a performance enhancing drug in the lead-up or aftermath of their May 2nd showdown at the MGM Grand in Las Vegas.

A positive PED test for either party would immediately kill the fight, place the offending fighter in line for a four year ban from competition, and also smack them with a very large financial penalty.

"If there's a positive test prior to the fight, the penalty for the fighter who violates it is going to be a lot higher than $5 million," Tygart said Friday to the AP.

Pacquiao's adviser Michael Koncz had pushed for a $5 million penalty for a positive test. Mayweather's camp, led by adviser Leonard Ellerbe, rejected the proposal - because they feels that a $5 million fine would limit the monetary scope of the damages. If Pacquiao failed a drug test, Mayweather would pursue damages for a much higher monetary amount.

Tygart said that if either fighter tests positive for a banned substance the results immediately would be given to the Nevada Athletic Commission. Both USADA and the NSAC would take disciplinary action together against the fighter in question.

"They signed on to the sanctioning process that is clearly spelled out," Tygart said. "It's a contract that would be enforceable against them."

Drug testing was the sole issue at hand when both parties attempted to make a fight in 2009/2010. Back then, negotiations fell apart when Pacquiao refused to take part in a random drug testing protocol.
