For the first time in the promotion’s history, a champion lost their title on weigh-in day after Oliveira was stripped of the lightweight belt on Friday having failed to make the 155-pound limit.
Gaethje can still win the title should he emerge victorious inside the octagon, although the crown would remain vacant should Oliveira triumph.
The co-main event sees Rose Namajunas battle Carla Esparza for the women’s strawweight title, while Michael Chandler and Tony Ferguson also square off in an eagerly-anticipated lightweight clash.

UFC 274 prediction
Gaethje will rarely have a better chance to take advantage of Oliveira, who couldn’t even make weight when afforded more time.
It’s hard to suggest all is well in the Oliveira camp and, as a result, Gaethje to beat him sounds the most likely outcome.
