A few of the biggest names in mixed martial arts will enter the octagon on Saturday night at UFC 196 in Las Vegas. The pay-per-view will be highlighted by the welterweight fight between Conor McGregor and Nate Diaz, and Holly Holm will make her first women’s bantamweight title defense in a fight against Miesha Tate.

McGregor has become the most popular fighter in UFC with his string of knockout victories, and his fight with Diaz should make for one of the best-selling pay-per-views in UFC history. The two fighters have been trading verbal barbs ever since Diaz replaced the injured Rafael dos Anjos last week, and their feud almost turned physical two days before their scheduled fight.

McGregor and Diaz had to be separated at a press conference on Thursday after the featherweight champ knocked away Diaz’s hand during their faceoff.

The main event will conclude a long night of fights at MGM Grand Garden Arena. The prelims begin at 8 p.m. ET on FOX Sports 1, and the PPV officially begins at 10 p.m. ET. The PPV fight card consists of five fights, including two light heavyweight fights and two women’s bantamweight fights.

Holm was in the main event of UFC 193, which reportedly sold over one million PPV buys, handing Ronda Rousey her first ever loss. Instead of waiting to defend her title when Rousey was ready to fight again in the second half of 2016, Holm will be back in the octagon less than four months later.

Tate has won four straight fights, last losing to Rousey in late 2013. But she was Rousey’s toughest opponent before Holm, lasting into the third round against the former champ.

Tickets for the event are still available through Ticketmaster. Ringside seats can be had for $1,454 each, and the cheapest seats cost $304.

UFC 196 is available on PPV for $49.99 in standard definition and $59.99 in HD. The PPV can also be purchased for the same price with UFC.TV, which allows fans to watch a live stream of the PPV with their phone, iPad or other devices.
