All eyes will be on Jon Jones, as the former Ultimate Fighting Championship titleholder returns to the Octagon for the first time since unlawful behavior outside the cage led to his being stripped of his crown.
Jones will face Ovince St. Preux -- he replaces the injured Daniel Cormier on short notice -- for the interim 205-pound championship in the UFC 197 main event on Saturday at the MGM Grand Garden Arena in Las Vegas. In the co-headliner, flyweight champion Demetrious Johnson risks his title against unbeaten Olympic gold medalist Henry Cejudo in a five-round clash at 125 pounds.
