Arizona bantamweight Roman Salazar came up the hard way with some of his region's best fighters, including Seth Baczynski and Efrain Escudero, and after making his name on the local circuit, he got a call from the UFC in 2014. 'El Gallito' won't just be facing any opponent, but one of Japan's best ever in the form of Kid Yamamoto. Back in action after three years away from the sport, the always exciting Yamamoto has done practically everything in the sport since turning pro in 2001, with the only thing eluding him thus far being a UFC win. Against Salazar, the 'Kid' looks to rectify that situation.

One of the most ferocious punchers in the UFC's heavyweight division, Derrick Lewis returns to the Octagon having earned his last eight victories by knockout, a stretch that includes UFC finishes of Jack May and Guto Inocente. It's a scary run for the Texan, but South Africa's Ruan Potts believes that he has what it takes to stop it. A fighting pioneer in his nation, Potts has come up short thus far in his UFC career, but with a solid ground game and fight-stopping power, he's determined to make sure that he ends the bout as the last man standing.

The biggest fight to be made in women's MMA will take place on Saturday, February 28th. UFC women's bantamweight champion Ronda Rousey defends her crown for the fifth time against No. 1 contender Cat Zingano at UFC 184 in Los Angeles. The unbeaten Rousey has ripped through all contenders at 135 pounds, needing just a combined 82 seconds to defeat Sara McMann and Alexis Davis in her two most recent title defenses. Colorado's Zingano is also undefeated as a pro, and after back-to-back knockouts of Miesha Tate and Amanda Nunes, she has plenty of momentum on her side.

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.

The Rio de Janeiro fight team known as Nova Uniao has produced some of the best mixed martial artists competing in the sport today, with the latest prospect to emerge from the camp being striking specialist Valmir Lazaro. The 29-year-old with nine of his 12 wins coming by knockout seeks his first UFC victory against James Krause. An experienced pro who can do it all on fight night, Krause has already put together two UFC wins over Jamie Varner and Sam Stout, but when you've had your hand raised in the Octagon, the more you win, the more wins you want.

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.
