Saturday, March 5 sees a huge grudge match headline a stacked fight card at the T-Mobile Arena in Las Vegas as Colby Covington and Jorge Masvidal get set to face off in the main event of UFC 272.

The two former friends and ex-training partners at American Top Team were once inseparable, but now they head into Sin City as bitter rivals after a rift that has left what seems like genuine animosity between the pair. Now they will settle the score by going head to head inside the octagon.

Also scheduled for action is a featherweight matchup between Edson Barboza and Bryce Mitchell, who both have their sights set on the top contenders at 145 pounds.

Ahead of the event, the UFC’s “Embedded” cameras are following the fighters behind the scenes as they work their way through fight week, from their final moments at home to their arrival in Las Vegas and their media obligations before the weigh-ins and the final faceoffs before fight night itself.

As described on the UFC’s official YouTube channel, on Episode 4, “Colby Covington connects with UFC champ Amanda Nunes; Jorge Masvidal chills at the UFC PI. Renato Moicano jumps at an opportunity. Bryce Mitchell enjoys the fight week experience.”
