While Joseph Benavidez and Demetrious Johnson are familiar names because of their exposure in both the Octagon and the WEC, their respective opponents at March's UFC on FX 2 -- Yasuhiro Urushitani and Ian McCall -- are UFC newcomers. So who are these guys that may be competing for UFC gold in 2012?

Ian McCall

Regarded as one of the top flyweights in the world, "Uncle Creepy" is coming up on his 10th year as a professional. Before his recent stint in the 125-pound haven known as Tachi Palace Fights, the 27-year-old McCall (11-2) spent time in the WEC as a bantamweight, going 1-2 with losses to Dominick Cruz and Charlie Valencia.

He's won four in a row and last was seen winning the Tachi flyweight gold with a third round submission win over Darrell Montague in August. In this current run, he also picked up wins over top flyweight Jussier da Silva and Dustin Ortiz, giving both their first career loss. He was set to defend his title for the first time but pulled out of a December 2nd fight with Josh Rave due to injury.

The Californian is also married, is a dad and has been known to sport as a very cool Rollie Fingers-style mustache.

Yasuhiro Urushitani

The 35-year-old has never competed outside of Japan and has been a fixture in Shooto nearly his entire 10-year career. The reigning Shooto bantamweight (123 pounds) champ has won five in a row with three out of the five coming via TKO. Mainly a decision fighter with 20 bouts going the distance, Urushitani (19-4-6) had a win over recent TUF winner and likely future flyweight John Dodson back in 2004.

Following UFC 140, Dana White announced that Urushitani will face Benavidez and McCall will fight Johnson at UFC on FX 2 with the winners competing for the first-ever UFC flyweight title.
