UFC 180 is the organization’s debut event in Mexico, and though the card has been riddled with injuries and is far from what was first announced, it’s still a historic event as the octagon sets up in a new country for the 15th time.

The third interim champion in UFC heavyweight history will be crowned as Fabricio Werdum (18-5-1 MMA, 6-2 UFC) and Mark Hunt (10-8-1 MMA, 5-2-1 UFC) collide in a five-round affair that will determine who will unify the titles with Cain Velasquez once he returns from a knee injury.

Werdum has spent several months acclimating to the brutal elevation needed to compete at Mexico City Arena, but Hunt has only had a little more than three weeks to prepare for the pay-per-view event after he stepped in for Velasquez on short notice.

A heavyweight fight has not headlined a UFC PPV since October 2013, but more than a year later, the organization’s largest division is back in the spotlight, and there’s plenty of numbers to digest.

For the figures behind Werdum vs. Hunt, as well as every other contest scheduled for the card, here are 50 pre-fight facts about UFC 180.
