Floyd Mayweather believes Manny Pacquiao's refusal to submit to blood testing is a sign that the Filipino doesn't want to fight him.

The bout between the two had been scheduled for March 13 but the deal is in danger of collapsing after a difference of opinion between the two camps.
Mayweather's team have insisted on US Anti-Doping Agency (USADA) protocols, including random blood tests at any point beforehand.
However Pacquiao has refused to be subjected to testing 30 days before the fight, believing that doing so would weaken him so close to the bout.
