LAS VEGAS – The UFC 279 fight card has been hit with mix-and-match changes unlike any pay-per-view before. After Khamzat Chimaev missed weight at official weigh-ins Friday morning, the promotion scrambled to repair key matchups on Saturday’s main card, including the creation of a new main event. Chimaev (11-0 MMA, 5-0 UFC) will no longer compete in the headlining bout and will face Kevin Holland in the co-main event of the card.
