Weidman is returning from two significant injuries, while Belfort is a different man entirely — no longer enhanced by the sanctioned steroid use that his critics feel contributed greatly to his incredible late-career surge. After three postponements, Weidman and Belfort are eager to close this prolonged chapter when they fight for Weidman's middleweight belt at the MGM Grand Garden. The UFC's traditional Memorial Day weekend event is stacked, with an undercard including ironman lightweight Donald "Cowboy" Cerrone, heavyweight contender Travis Browne, the return of "The Ultimate Fighter" standouts Rose Namajunas and Uriah Hall, and two flyweight bouts with championship implications: No fight has been more anticipated than Belfort's attempt to become just the third fighter to hold UFC belts in two weight classes. Several years after getting busted in the Pride promotion in 2006, he gleefully used testosterone replacement therapy that was allowed at the time, but eventually banned in the sport for its obvious competitive advantages. Weidman says the UFC considered staging an interim title bout, as it did in the heavyweight division after champion Cain Velasquez's repeated injury woes.
