Contract signed: Mosley-Mayweather set for May 1: Mosley has agreed to the testing Mayweather requested. Both fighters will be subject to random blood and urine testing which will be administered to the U.S. Anti-Doping Agency. "Floyd tried to fight the guy everyone thought was the best guy available and we couldn’t get that fight done, so we went to the next guy on the list," Mayweather Promotions CEO Leonard Ellerbe said. "As I’ve said many times, when Floyd decided to come back to boxing, he did it to be in major events. He’s going to face all of the top welterweights and one by one, knock them all off."
