The UFC has announced the main event of their first show on FX, and it is a good one. In a Lightweight fight, it will be Jim Miller vs. Melvin Guillard. The UFC confirmed the fight via Twitter earlier today. 

Miller vs. Guillard is a really well booked fight between two Lightweights who were just recently on the verge of title contention. Both men were on the short list of possible next challengers to Frankie Edgar, only to suffer somewhat surprising loses. For Miller, that loss came at the hands of Ben Henderson at UFC Live on Versus 5 this summer, while Guillard was defeated by Joe Lauzon at UFC 136. A win for either man will move them back towards the top, while a loss will put one on a two fight losing streak. It's a huge fight for both men.

Two other interesting notes here. First up, it's worth noting that this is announced as the main event. After Lightweights Clay Guida and Ben Henderson were only on the prelims for the big Fox debut, here the Lightweight fight is being given the spotlight. Second, this is only three rounds. It wasn't long ago that Dana White stated clearly that all main events would be five round fights moving forward, but so far, only Chris Leben vs. Mark Munoz at UFC 138 has actually been a non-title five rounder. What is the hold up?

UPDATE - It looks like, while the fights are set, the logistics of the card are still coming together. The show was originally discussed as taking place on January 20 in Nashville,TN as we previously reported, however there are now reports that it could be held in Sydney, Australia in the afternoon of Jan. 21 and broadcast live to the US. No confirmation yet from the UFC on this. Check back for more updates as we have them.
