The night UFC fans have been waiting for finally is here. Featherweight champion Conor McGregor will headline a stacked UFC 196 card Saturday night in Las Vegas, where he will fight up two weight classes to faces Nate Diaz as a welterweight in the main event. Joining him on the main card is women’s bantamweight champion Holly Holm, who will return to the octagon for the first time since her shocking upset over Ronda Rousey. Holm’s title will be up for grabs in the co-main event against Miesha Tate. The main event will kick off at 10 p.m. ET on pay-per-view, but fight fans will have plenty of preliminary bouts to hold them over
