LAS VEGAS (AP) — While Floyd Mayweather Jr. sat in a jail cell, rapper 50 Cent set about signing fighters and putting together the promotional company he and Mayweather had long talked about.

It seemed like a perfect match for two buddies who liked nothing better than to have HBO cameras film them playing with stacks of $100 bills in the “24/7” series. But it fell apart when Mayweather got out of prison and decided that he would rather play with his money than invest it in a boxing company.
