Floyd Mayweather Jr. credits 'estranged' dad for boxing career longevity

World boxing champion Floyd Mayweather has credited his father for his longevity in boxing.

CNN reports that the pair was professionally reunited for the first time in 13 years as Floyd Sr. worked the corner during his son's successful welterweight title defense against Robert Guerrero.

According to the report, the intervening years had been characterized by bitter rows and public slanging matches.

Floyd Jr. volunteered the help of his father since he returned to the ring in May after serving a two-month jail term for a domestic violence conviction.
