Mike Tyson is warning 50 Cent that boxing is like no other business. The rapper recently announced his partnership with boxer Floyd Mayweather Jr. called the Money Team Promotions, and Tyson says he wishes 50 the best of luck. But he explained during an interview with Entertainment Sports Radio that boxing is about, quote, “dealing in flesh,” and anyone in the business has to be ready for anything. Tyson adds that even with 50’s skills as a rap star, entertainer, and entrepreneur, he still “doesn’t really know the ins and outs of boxing.” He says Mayweather is probably helping, but Tyson warns that once 50 “gets in this arena, everyone that was ever his friend on the other side is [now] his enemy.”
