The tragic news comes less than a week since Mayweather’s ex-girlfriend and mother of their three children Josie Harris was found dead in her car at the age of 40.

Roger Mayweather, a Michigan native, became a distinguished world champion in his own right, facing both Julio Cesar Chaves Jr and Pernell Whittaker during a 20-year career, before establishing himself as one of the greatest coaches in the sport’s history.

“Roger was a great champion and one of the best trainers in boxing. Unfortunately, his health was failing him for several years and now he can finally rest in peace.

Nicknamed the “Black Mamba”, Mayweather Sr won 59 of his 72 professional fights, capturing the WBA super-featherweight world title and WBC light-welterweight world title.

He began working with his nephew Floyd in the late ‘90s and moulded him into one of the greatest pound-for-pound fighters of all time over the course of 12 years, boasting an unbeaten 50-0 record.
