The UFC totally rearranged the main three battles on its UFC 279 card,
UFC President Dana White told SportsCenter in a live Instagram video on Friday.
Nate Diaz will currently confront Tony Ferguson in the headliner of Saturday's show at the T-Portable Field.
Diaz's unique adversary, Khamjat Chimayev, dropped 7.5 pounds Friday morning.
Came in at 178.5 pounds in a 171-pound-limit battle.
Diaz naturally decided not to battle such an overweight adversary.
Chimaev began squeezing and securing while at the same time getting in shape, White said.
"It's anything but a fortuitous event that we stack folks of a similar load on a similar card in the event that something turns out badly.
It worked," White said.
