Mayweather has already agreed to Pacquiao's demand of 10 million over the welterweight limit, it's time for Manny to agreed to this part of the bargain of blood testing. And it's only a tablespoon of blood, not that much to affect Pacquiao.

"We're not talking about a lot blood, just a tablespoon," said Schaefer, who reiterated he is not accusing Pacquiao of any illegal drug use. "For someone that is in the public eye the way Pacquiao is, he should be held to the highest standard of drug testing. That's all we are asking for."
