While Conor McGregor has grabbed headlines in recent days surrounding his "retirement," there still remains plenty of active talent in UFC. Jon Jones, the No.1 light heavyweight contender, faces Ovince Saint Preux in the main event of UFC 197 on Saturday night at the MGM Grand Garden Arena in Las Vegas.

Jones had been scheduled to face Daniel Cormier for the title he vacated last summer, but an injury forced Saint Preux to fight in Cormier's place. If Jones wins, as many expect him to do, it could potentially set up a rematch with Cormier at UFC 200 on July 9.

Jones has never lost by submission, knockout or judges’ decision in his mixed martial arts career. He’s a heavy favorite to get his 22nd victory, though he could be affected by such a long layoff. Because of legal issues, Jones hasn’t been in the octagon since he beat Cormier to retain the light heavyweight championship on Jan. 3, 2015.

 While McGregor is coming off a loss in his last bout, Jones has been one of UFC's dominant fighters, as well as one of the company’s top pay-per-view draws. His fight against Cormier reportedly generated somewhere between 700,000 and 800,000 PPV buys.

Demetrious Johnson is also on the card, defending his flyweight championship against Olympic gold medal winner Henry Cejudo. UFC ranks Jones and Johnson as the No.1 and No.2 pound-for-pound fighters, respectively.

The PPV cost $69.99 to order in HD. Fans can also watch the fight with a live stream online by purchasing the event with UFC.TV for $59.99.
