This weekend's fight night event in Macau has some sneakily good match-ups from top to bottom but one fight that couldn't possibly go under the radar is the main event.

In a top five bantamweight match-up at the Galaxy Arena, two former champions will face off in one of the most exciting clashes of styles possible.

Former flyweight king Deiveson Figueiredo has hit the ground running since moving up to 135-pounds following the conclusion of his quadrilogy with Brandon Moreno.

"Deus Da Guerra" has beaten Rob Font, Cody Garbrandt and Marlon Vera to earn this first main event spot for him at bantamweight where he will face a former titleholder in this division.

Russia's Petr Yan rebounded from three consecutive losses last time out by beating Song Yadong at UFC 299 but halting the win streak of his next opponent will really put "No Mercy" back in the mix.

In the co-main event, former title challenger Yan Xiaonan defends her #2-ranking against Tabatha Ricci in the #10-spot who has secured back-to-back wins over Tecia Pennington and Angela Hill.

Along with Xiaonan, Chinese talent like Kenan Song, Cong Wang and Mingyang Zhang will all feature on the main card.

A top 10 match-up at light heavyweight is also set for the card as Carlos Ulberg looks to continue his winning streak against Volkan Oezdemir who finished Johnny Walker back in June.

The prelims feature three finals of this year's Road To UFC tournament with new champion's set to be crowned at bantamweight, flyweight and strawweight.

A highly anticipated Octagon debut will also take place on the prelims as Lone'er Kavanagh makes his UFC debut when he faces Jose Ochoa following an incredibly impressive performance on Dana White's Contender Series in August.
