Rapper and entrepreneur 50 Cent is taking a swing at promoting boxing in Nevada.

Nevada Athletic Commission executive Keith Kizer said Monday the entertainer and businessman whose real name is Curtis James Jackson III won approval last week for a promoter's license.

The company is called SMS Promotions. It's handling a Dec. 8 bout at the MGM Grand Garden Arena in Las Vegas between Cuban-born Miami-based boxer Yuriorkis Gamboa and an opponent yet to be named.

Messages left Monday with the company in New York City weren't returned.

Kizer says 50 Cent and boxer Floyd Mayweather Jr. had been talking about forming a promotions company called TMT Promotions.

But the rapper told the commission those plans fell through, and the fledgling business was being absorbed by SMS Promotions.
