The UFC is in Brazil again for Saturday's UFC on FX bouts. The top of the card holds a contentious bout between two fighters who clearly don't like each other. What do you need to know before tuning in?
Will Luke Rockhold keep octagon jitters at bay? Luke Rockhold spent most of his career in Strikeforce. He worked his way up through the challengers system to become the promotion's final middleweight champion. Now, he finally gets a chance to show he belongs in the UFC. He won't have an easy entry, fighting Vitor Belfort, who is coming off of a TKO win over Michael Bisping in January. Will he avoid octagon jitters and keep his fight streak alive?
Has Ronaldo "Jacare" Souza continued to grow as a fighter? Souza well-credentialed in jiu-jitsu, but his fight game has become more well-rounded in recent bouts. He'll face Chris Camozzi, who is on a four-fight win streak. Will Souza show the complete fight game he did in Strikeforce?
Is Nik Lentz among the best of the loaded featherweights? Since dropping down to 145 lbs., Lentz is 2-0. He'll face Hacran Dias on his home territory. Both fighters have a chance at getting closer to Jose Aldo and the featherweight belt with a win. Which one will come away the winner?
