UFC on FOX 31 goes down this weekend live from the Fiserv Forum in Milwaukee, WI! In the main event, lightweights Al Iaquinta and Kevin Lee will go to war in a UFC 169 rematch. Underneath the pair, all over the card, people are wanting to make a mark with promoters and fans. With uniforms now de rigeur for UFC athletes, one of the few ways they have left to stand out as individuals is with walkout music. Some have a had low-energy entrances.
