The UFC makes their grand debut on FX this Friday.
The event will be highlighted by an exciting lightweight matchup featuring Melvin "The Young Assassin" Guillard against Jim Miller.
Both fighters have hit a stumbling block recently in their careers.
Guillard was on his way up the lightweight rankings with five straight wins, including three finishes. That was until he ran in to Joe Lauzon at UFC 136. Guillard was submitted via rear-naked choke in the first round.
Miller was also on the doorstep of a lightweight title shot when he was matched up against former WEC lightweight champion Ben Henderson. Henderson was able to pull off the decision victory over Miller and is going on to face Frankie Edgar for the UFC lightweight championship.
Both lightweights will be looking to get back on track to a title shot, but they'll need to get through one another first.
Here are five things to watch for during the main event.
