Floyd Mayweather Sr. Fights Ruben Guerrero Outside Of Las Vegas Boxing Gym: Fathers Of Floyd Mayweather Jr., Robert Guerrero Brawl [VIDEO]

The father of welterweight boxing legend Floyd Mayweather Jr. was involved in a fight with the father of another prominent boxer outside a Las Vegas gym, according to a report.

Floyd Mayweather Sr., 61, came to blows Wednesday with Ruben Guerrero, the father of interim WBC welterweight champion Robert Guerrero, TMZ reports. The fight reportedly occurred as both men were scheduled to film scenes for an upcoming reality television show about boxing.

The cause of the fight is unclear, but TMZ notes that the skirmish was not scripted and had no connection with the reality show. During the 40-second clip, a large group of men can be seen separating Mayweather Sr. and Guerrero. At one point, Mayweather Sr. pushed his way through the crowd and threw several punches at Guerrero before the two men were separated for a second time. Mayweather Sr.’s punches did not appear to hit their target.

This isn’t the first time the Mayweathers and the Guerreros have been at odds. Ruben Guerrero referred to Floyd Mayweather Jr. as a “woman beater’ in the days leading up to the latter’s bout against his son last May, Larry Brown Sports notes. Ultimately, Mayweather Jr. won that fight by unanimous decision.
