Reigning UFC lightweight king Oliveira (32-8, 1 NC, fighting out of Houston, Texas by way of Sao Paulo, Brazil) intends to further his legacy as champion by taking out one of his toughest opponents to date. The record holder for most UFC finishes, submissions and post-fight bonuses, Oliveira has established himself as one of the most exciting athletes on the entire roster. He is also currently on a 10-fight win streak, which includes notable victories over Dustin Poirier, Kevin Lee and Jim Miller. Oliveira now looks to defeat another top contender and continue his rise up the pound-for-pound ranks.

Former interim champion Gaethje (24-3, originally from Safford, Ariz., and fighting out of Arvada, Colo.) is one of the only lightweights that can match Oliveira's impressive finishing ability. An NCAA All-America wrestler, he has earned nearly all his victories by knockout, including wins over Michael Johnson, James Vick and Edson Barboza. He now plans to put Oliveira's resolve to the test and finally capture his first undisputed UFC title.

UFC strawweight titleholder Namajunas (12-4, fighting out of Denver, Colo.) returns to action seeking to successfully defend her belt for the second time by avenging her 2014 loss against Esparza. Among the most popular athletes on the UFC roster, she holds the record for most stoppage wins in strawweight history, including victories over former champions Joanna Jedrzejczyk and Zhang Weili. Namajunas now aims to leave no doubt that she is the best 115-pounder on the planet with a statement performance.

Esparza (19-6, fighting out of Irvine, Calif.) has her sights set on regaining her strawweight championship by replicating her submission victory over Namajunas. Currently on the longest win streak of her UFC career, she secured her shot at the crown with memorable performances over Yan Xiaonan, Marina Rodriguez and Michelle Waterson. Esparza is now determined to prove that her first win over the champion was no fluke and begin her second reign atop the division.

Chandler (22-7, fighting out of Nashville, Tenn.) has wasted little time in cementing himself as a must-see fighter since joining the UFC roster. Already a highly regarded competitor before entering the stacked UFC lightweight division in 2021, he quickly ascended to the top of the ladder following a highlight reel KO over Dan Hooker. Chandler now expects to repeat the success from his debut by finishing Ferguson with a statement performance.

Fan favorite Ferguson (26-7, fighting out of Orange County, Calif.) has been entertaining audiences with his unique fighting style since winning season 13 of The Ultimate Fighter in 2010. A Brazilian Jiu-Jitsu black belt, Ferguson won his own interim UFC title by putting together the longest win streak in lightweight history with 12 consecutive victories, including wins over former title holders Anthony Pettis and Rafael Dos Anjos. He now is gunning to get back on track and reinsert his name into the championship conversation by taking out Chandler.
