Mayweather blame Pacquiao for collapse of bout

Mayweather blame Pacquiao for collapse of bout and is claiming that the Filipino boxer refuses to accept a reasonable compromise on drug testing concerns.

Mayweather initially demanded repeated blood testing right up to the day of the fight, while Pacquiao asked for a 30-day cutoff before the bout. Mayweather now claims he agreed to a 14-day cutoff compromise before the mediation session began, but Pacquiao still wouldn't accept those terms.

Pacquiao has filed a lawsuit alleging Mayweather and most of his representatives, including Golden Boy Promotions CEO Richard Schaefer, defamed him by falsely accusing him of using performance-enhancing drugs.

Top Rank boss Bob Arum says that Mayweather is "a psychological coward who doesn't want to fight anybody who has a chance of beating him."
