The Ultimate Fighting Championship on Saturday returns to Fortaleza, Brazil, with an intriguing card stacked with prospects and borderline contenders in need of breakthrough wins. At the top of the show, hometown hero Vitor Belfort looks to regain his status as a middleweight contender by taking out Kelvin Gastelum, whose weight cutting issues forced him to the 185-pound division. Light heavyweights Mauricio Rua and Gian Villante square off in the co-main event, their respective careers headed in opposite directions. Meanwhile, lightweight show-stealers Edson Barboza and Beneil Dariush clash on the main card -- a fight which could easily vault either man into title contention.
