Reached late Tuesday night, Bob Arum of Top Rank, which promotes the Filipino, took it a step further.
"The plug is pulled. The fight is off as far as we're concerned," he said, adding that he expects Pacquiao to fight on that date but is seeking a new opponent.
"All they're doing is harassing Pacquiao. I'm not going to allow it to happen," Arum said. "We're willing to do urine analysis at random even though we don't have to do it under Nevada rules. … I know deep down Mayweather doesn't want the fight. He can take a walk."
