With the cancellation of the previous UFC 130 main event of Frankie Edgar vs. Gray Maynard, Frank Mir's bout against Roy Nelson gets promoted as the co-headliner of the event. Now, Mir tries to sell the fight with a few statements that are guaranteed to get people talking. He issued a warning to his opponent (transcribed by MMAMania):
"Fights that I've seen of Roy when people do well against him is when they move forward. If he makes a mistake ... I'm a lot bigger than (Junior) Dos Santos and I hit a lot harder. I'm a taller, longer athlete, quicker. I'll constantly pepper him with shots when he comes in and make him pay when I do hit him with something. When I hit Cheick Kongo, the punch alone threw him halfway across the Octagon. On the night of the fight, neither one of us are gonna pull any punches. If I catch him with something, I'll try to hurt him with it."
