On one of the craziest nights in the history of the promotion, the UFC 279 card completely fell apart after Khamzat Chimaev missed the non-title welterweight mark by 7.5 pounds.In a move that is being called brilliant by some fans and "scripted" by others, the UFC set up Nate Diaz to fight fellow veteran Tony Ferguson.Ariel Helwani@arielhelwaniThis feels like one of those cool photoshop videos6555408This feels like one of those cool photoshop videos https://t.co/Jo8LXaVB9AThe lineup shuffle also saw Chimaev booked against Kevin Holland.

However, veteran MMA journalist Ariel Helwani revealed that it is not Dana White who deserves the credit, but Hunter Campbell.Ariel Helwani@arielhelwaniThe UFC MVP who saved this card wasn’t Dana White. Don’t listen to the media guys who are spinning that narrative. It was Hunter Campbell. He saved it for them and deserves the credit.173561043The UFC MVP who saved this card wasn’t Dana White.

While at it, he also took a sly shot at Khabib Nurmagomedov for ducking Tony Ferguson:"Tony’s been around a long time, we should have fought a long time ago. Khabib's [Nurmagomedov] b**ch a** was afraid of him just like this b**ch a** motherf***er was afraid of me yesterday. We punched his b**ch a** in the back here and now he doesn’t make weight. You guys already know what it is. Real Gs come from California, America motherf***er."Watch the promo below:Ariel Helwani@arielhelwaniWhat a promo424476794What a promo https://t.co/SAjvZXqMu0This is the first time in the history of the promotion that a main event had to be changed due to a fighter missing weight. However, Chimaev will not be fined since he is getting ready to face Kevin Holland at an official catchweight of 180 pounds. The other two fighters on the card who missed weight - Chris Barnett and Hakeem Dawodu - will have to forfeit a percentage of their purses.Kevin Iole@KevinIFor those asking, Khamzat wasn’t fined for missing weight. He’s in a new bout at a catchweight and he made that weight. So fines for Dawodu and Barnett because they missed weight and are fighting same opponent. Khamzat is fighting a 180-pound catchweight, so no fine. #UFC279395For those asking, Khamzat wasn’t fined for missing weight. He’s in a new bout at a catchweight and he made that weight.
