This just adds more fuel to the fire for the bout in my opinion. Imagive the PPVs these guys could do with all the hype surrounding the bout now!

Manny Pacquiao said he plans to file a defamation lawsuit against Floyd Mayweather Jr., the fighter’s father, and Golden Boy Promotions.

In a statement posted yesterday on his Web site, Pacquiao claims that his character has been damaged and tarnished by accusations he says are untrue. Floyd Mayweather Sr. repeatedly has accused Pacquiao of taking illegal substances, according to ESPN.com.

“Enough is enough,” Pacquiao said in the statement. “These people, Mayweather Sr., Jr., and Golden Boy Promotions, think it is a joke and a right to accuse someone wrongly of using steroids or other performance-enhancing drugs. I have tried to just brush it off as a mere pre-fight ploy, but I think they have gone overboard.”

A planned March 13 fight in Las Vegas is in danger because the sides have failed to find a compromise to a dispute over blood testing. Promoter Bob Arum declared the bout dead Thursday.

At the core of the dispute is the insistence of the Mayweather camp on using Olympic-style drug testing for the fight, even though both fighters have never been linked to any performance-enhancing substances.

Arum had set a Thursday deadline for an agreement on testing. With the Mayweather camp still insisting on using the U.S. Anti-Doping Agency to conduct the tests, Arum said there wasn’t much left to discuss.
