Josh Barnett talks training and the Heavyweight Grand Prix. Barnett will face the heavy-handed Brett Rogers in a quarterfinal showdown! The 6-foot-3, 255-pound Barnett became the youngest UFC champion in history at age 24 when he scored a second-round TKO (4:35) on MMA legend Randy "The Natural" Couture in Las Vegas, Nev., on March 22, 2002. In his sixth career fight, Barnett submitted wrestling and MMA legend Dan "The Beast" Severn with an armbar in the fourth round (1:21) in Hawaii. In addition to his achievements in America, Barnett has spent a good portion of his career competing in top tier promotions overseas, including the now defunct PRIDE Fighting Championships in Japan where he notched memorable victories over the likes of Aleksander Emelianenko, Mark Hunt and Antonio Rodrigo Nogueira. On Oct. 21, 2006, Barnett took part in PRIDE's first event on U.S. soil, submitting Pawel Nastula with a toe hold in the second round (3:04) at Las Vegas's Thomas & Mack Center.
