FC 274 has already started in the most dramatic of fashions.
For the first time in the promotion’s history, a champion has been stripped of their title on weigh-in day, with Charles Oliveira failing to make weight ahead of his clash inside the octagon in Justin Gaethje.
It is the fifth time in the Brazilian’s career he has failed to make weight and could not even do so when afforded more time.
The event will still go ahead but the dethroned champion is unable to retain his title, although Gaethje will reach undisputed level if he emerges victorious.
The co-main event sees Rose Namajunas battle Carla Esparza for the strawweight title.
