Pacquiao / Mayweather - Round 1

Manny Pacquiao is threatening to sue Floyd Mayweather for defamation after Paquiao refused to take a blood test days before a boxing match between the pair. Mayweather has suggested that the reason Pacquiao is refusing the test is because he's in with A-Rod's trainer. Pacquiao's camp has repeatedly insisted that the reason he will not take the drug test is that blood testing just days before the match will compromise his training.
