"The untimely injury of heavyweight champ Cain Velasquez in late October nearly derailed the UFC's first event in Mexico.
"Fortunately for the company's brass, fearless and ambitious heavyweight contender Mark Hunt stepped up on late notice to replace Velasquez and subsequently accept a daunting task in the night's main event.
"The fourth-ranked Hunt will face top-ranked submission wizard Fabricio Werdum in an interim heavyweight title bout in the main event Saturday night at UFC 180 at the Arena Ciudad de Mexico in Mexico City.
"On a top-heavy card that includes fourth-ranked featherweight Ricardo Lamas and seventh-ranked welterweight Jake Ellenberger, the matchup between Mark Hunt and Werdum could prove a perfect ending to a captivating night."
