The UFC is working on finalizing the 155-pound title fight shortly. The pay-per-view event now includes two title fights. Brazilian light heavyweight champion Glover Teixeira will face Jiri Prochazka on the same date.
The UFC has not announced an official venue. It had considered holding it in Brazil, but the card is now expected to take place in the U.S.
Oliveira (32-8) is coming off a spectacular year in 2021. The 32-year-old from Brazil won the vacant title by knocking out Michael Chandler in the second round of an exhilarating title fight in May, and finished off the calendar year with a comeback submission victory over Dustin Poirier for his first title defense.
Gaethje (23-3) has been waiting for another crack at UFC gold since former champion Khabib Nurmagomedov retired in October 2020. Gaethje, of Arizona, challenged Nurmagomedov for the title in the final fight of Nurmagomedov's career. His record made him worthy of fighting for the vacant title right away, but he was forced to pick up one more win before earning the shot.
That win came against Chandler in November at UFC 268 at Madison Square Garden, where Gaethje won the bout via decision.
