Conor McGregor's UFC Return Expected to Be Record-Setting $200 Million Fight

Conor McGregor’s return to the octagon has UFC executives expecting the most lucrative fight by far in the promotion company’s quarter-century history.

McGregor’s two-year hiatus from mixed martial arts, which began with a disagreement over money and included a lucrative dip into boxing, ends Saturday night when he fights undefeated Khabib Nurmagomedov in Las Vegas.
