The main event of UFC 221 almost never came to be. After middleweight champion Robert Whittaker was forced out of action with a staph infection, his replacement, Yoel Romero, missed 185-pound limit for his bout with former champion Luke Rockhold.

After brief negotiation, the two sides agreed to keep the fight on with Rockhold taking a portion of Romero's paycheck, according to MMAFighting.com. Thankfully for our friends on the other side of the globe, the show will go on from Perth, Australia.

In the co-main event of the night, a showdown between two top-10 heavyweights will take center stage as No. 5-ranked contender Mark Hunt will take on No. 9-ranked Curtis Blaydes. The 26-year-old Blaydes, who's riding a four-fight win streak in the UFC, will look to make an even bigger name for himself if he can pull off the upset of a veteran the caliber of Hunt. With the heavyweight division needing some contenders, Blaydes has a chance to really make a name for himself with a win on Saturday and climb up the rankings. 

Here's all the information you need to catch the UFC 221 action live on Saturday night in Australia.
