UFC 184: Rousey vs. Zingano - Prelims

A former world title challenger with dynamite in his fists and a world-class wrestling attack to lean on if he needs it, Josh Koscheck is back in the Octagon for the first time since a 2013 loss to Tyron Woodley, and this seasoned vet is more determined than ever to get back on the right track and make a title run. A near mirror image of Koscheck in terms of punching power and wrestling ability, Nebraska's Jake Ellenberger wants to set himself apart by halting his opponent's comeback in its tracks and making a statement that in 2015, 'The Juggernaut' will not be stopped.

A veteran member of the UFC roster, Brazilian Jiu-Jitsu ace Roan Carneiro didn't have the success he wanted in the Octagon the first time around, despite wins over Rich Clementi and Tony DeSouza. Yet with wins in seven of his next eight bouts outside the UFC, 'Jucao' is back among the best in the world and he's ready to prove himself once more. Eager to begin 2015 with a return to form in one of the sport's most competitive divisions, Mark Munoz has amped up his training in Southern California and in his first local appearance since 2010, 'The Filipino Wrecking Machine' plans on unleashing the ground-and-pound that earned him his nickname.

Owner of the most wins in UFC lightweight history, Gleison Tibau is showing the best form of his career at 31, with consecutive victories over Pat Healy, Piotr Hallmann and Norman Parke. He will seek his second win of 2015 at UFC 184 and make his case for a spot in the top 15. Fighting out of Southern California, former Ultimate Fighter winner Tony Ferguson will get a home game tonight against Tibau, and with four consecutive wins since October of 2013, 'El Cucuy' can secure a place in the top ten with another impressive victory.

One of Colombia's top wrestlers, Alex Torres has turned into one of his country's top mixed martial artists, a gutsy competitor who first made a mark on the international scene with his appearance on The Ultimate Fighter Latin America. The hard-hitting featherweight prospect makes his UFC debut against his TUF castmate, Masio Fullen. Despite losing on The Ultimate Fighter Latin America to eventual finalist Leonardo Morales, Team Velasquez' Masio Fullen returns to battle as a UFC fighter, and after wins in three of his last five pre-TUF bouts, with each victory coming before the final bell, the Mexican standout is an exciting addition to the roster.

Fighting out of Los Angeles, California, Alan Jouban has only competed in two fights in the UFC thus far, but in that short amount of time, he's become a fan favorite for his all action style and will to win. Owner of a Fight of the Night knockout win over Seth Baczynski, Jouban is aiming to put on a show and get a win over Richard Walsh. Australia's Richard Walsh is known to have an impressive ground attack, but nothing pleases 'Filthy Rich' more than a stand-up battle, and that's just what he's traveled to the United States for, and this time he plans on leaving the judges out of the final verdict.
