After beating UFC star Conor McGregor, Mayweather retired from professional boxing in 2017. UFC president Dana White also announced 50 Cent kickstarted the crossover match talks, after telling him that Floyd wanted to defeat McGregor. Mayweather returned to Japan for an exhibition where he knocked over featherweight kickboxer Tenshin Nasukawa. And, despite the event shifting from its original February date, he is set for a similar spectacle battle against YouTuber Logan Paul. 50 Cent was an ever-present part of his entourage, in training camps and on fighting nights, for most of Mayweather's career. The music artist would rap the legend of boxing into the ring and featured prominently in the '24/7' series behind the scenes of HBO. But Jackson claims to have helped set up The Money Team in 2012 when Mayweather went to prison and says he was owed $2 million. After Mayweather was released and showed no signs of paying up, according to 50 Cent, the trouble began. Despite the 50-0 icon topping, Forbes' rich list of the decade with a £ 706m fortune, Jackson has repeatedly accused Mayweather of running out of money.
