Charles Oliveira has been stripped of his lightweight title ahead of UFC 274 after failing to make weight.
It is the first time in UFC history a reigning champion has lost their title on weigh-in day and the fifth time in his career the Brazilian has failed to make weight.
Scheduled to meet Justin Gaethje inside the octagon, even a win for Oliveira would result in the title remaining vacant.
Title fights in the UFC do not permit the one-pound allowance typically afforded in non-championship bouts.
Oliveira won the title while vacant in May 2021 after beating Michael Chandler and defended it against Dustin Poirier at UFC 269.
Granted an extra hour after failing to cut down to 155 lbs, the 32-year-old could not make it, weighing in at 155.5 lbs in front of a shocked crowd in Phoenix, Arizona.
