After a bit of a curveball, UFC 251 may have gotten its rightful main event. Kamaru Usman will defend his welterweight title against Jorge Masvidal in the main event on Yas Island in Abu Dhabi on July 11, after Gilbert Burns tested positive for the coronavirus on Friday. 

There's still many hurdles to clear (just like the rest of the fight card) including three more COVID-19 tests, but the fight was officially announced by the promotion late Sunday night as the new main event for Fight Island.

With 48 career fights under his belt, Masvidal would serve as the fighter with the most MMA appearances before receiving his first title shot. 

After a brief moment as the main event, Alexander Volkanovski vs. Max Holloway 2 will go back to its original placement as the co-main event with the featherweight title on the line. Volkanovski is on as strong a run as any at 145 pounds with 18 straight wins dating back to 2013, including the decision over Holloway to claim the belt. Holloway, meanwhile, will look to get back on the winning track after a 1-2 2019. Before that, he was on a Volkanovski-type run, going undefeated for five years and claiming the title with two wins over Jose Aldo.

Plus, a pair of important women's fights round out the main card. Top strawweight contenders Jessica Andrade and Rose Namajunas will finally meet for their rematch after being scheduled to fight at UFC 249 in April. Namajunas was forced to withdraw when two family members died from COVID-19, according to her manager. Kicking off the main card will be a women's flyweight scrap between Paige VanZant and Amanda Ribas. It is reportedly VanZant's final fight on her UFC contract.

Let's take a look at the complete fight card for UFC 251.
