The boxing world lost an enduring name, and one of its most famous families must now grieve one of its own. Roger Mayweather, a former fighter who went on to earn worldwide acclaim training his nephew, five-division world champion Floyd Mayweather Jr., has passed away, as confirmed by his family to TMZ.

He was 58 years old.

A fighter who compiled 72 professional wins across four weight classes, "The Black Mamba" won world championships in the 130- and 140-pound divisions, becoming the lineal champion in the former in 1983. He is best known today, however, as the man who helped his brother Floyd's son achieve all-time superstardom.

From 1996-1998 and then again from 2000-2012, Roger trained Floyd Mayweather Jr. He contributed directly to his nephew's rise to becoming the world's highest-paid athlete and one of the most recognizable figures in global sport. By the time Roger left Floyd Jr.'s corner, "Money" was 43-0 as a pro and had claimed titles in every division from 130 pounds all the way up to 154.

In recent years, Roger moved further away from the public eye as the effects of his boxing career took an increasing toll on his health.

Floyd Mayweather and his family were already reeling from the shocking death of Josie Harris, his former gilfriend and the mother of three of his children, who was found dead in her car last week at the age of 40. Now, the family must reckon with another tragic passing that came far, far too soon.

Our thoughts are with the family as they navigate this most difficult of times.
