Pacquiao threatens Mayweather with lawsuit

SARANGANI, Philippines (AP) - Manny Pacquiao says he is planning

to file a defamation lawsuit against Floyd Mayweather Jr., the

fighter's father, and Golden Boy Promotions.

In a statement posted Friday on his Web site, Pacquiao claims

his character has been damaged and tarnished by accusations he says

are untrue.

The proposed megafight between Pacquiao and Mayweather 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.

Arum set a Thursday deadline for an agreement on testing, the

only issue not resolved for the planned March 13 fight. But 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.
