Tempers flared again on the set of NUVOtv's new boxing reality show Knockout. For the second time in less than a week, trainers Floyd Mayweather Sr. and Ruben Guerrero had to be physically restrained from one another after a war of words became physical. The two trainers nearly brawled on Sunday night during a private dinner for the show.
Their feud first began when their sons, Floyd Mayweather Jr. and Robert Guerrero, agreed to face each other last May in Las Vegas. The two trainers bickered quite often in the weeks leading up to the fight, which Mayweather won by way of a lopsided decision.
