Taking main event status tomorrow night at the UFC Apex facility, the middleweight clash between former champion, Robert Whittaker and The Ultimate Fighter victor, Kelvin Gastelum is official — with both weighing below the 186-pound limit for a non-title fight.

Removed from the card entirely in the last few moments, the 139-pound catchweight matchup between Zarah Fairn dos Santos and Joisane Nunes has been shelved, after the former tipped the scales at 147-pounds. The event will now proceed with eleven bouts.
