Charles Oliveira looks to continue his reign as lightweight champion whilst former interim titleholder Justin Gaethje looks to win his first undisputed title at UFC 274 in Arizona.
In a clash of two polarising styles, submission specialist Oliveira has the most submissions in UFC history whilst Gaethje is known for being one of the hardest strikers in the division. Oliveira is unbeaten in his last 10 fights whilst Gaethje has only lost one of his last six.
Strawweight champion Rose Namajunas makes the second defense of her title in the co-main event against old rival Carla Esparza. The pair fought eight years ago when Esparza submitted Namajunas to win the 115-pound belt.
Also on the stacked event is a guaranteed thriller of a fight between Michael Chandler and Tony Ferguson. Crafty veteran Donald Cerrone is also in the action, so here's all your cageside guide for the card...
What time does Oliveira v Gaethje start?
The main event between Oliveira and Gaethje will likely get underway around 5:30am for UK fans.
This depends on the result of the undercard fights and it could be later than that as the co-main event features a five-round title fight as well.

Quotes corner
Charles Oliveira: "He's a very tough guy, has very heavy hands. A guy who likes to walk forward all of the time, he likes to fight and is a brawler. I'm a guy who always has my feet on the ground, I'm not worried about who's on the other side I'm worried about what I can bring to the octagon.
"Knowing there is a very tough guy on the other side who deserves all the respect in the world, but the champion has a name and that's Charles Oliveira. I'm not worried so much about taking him down, I believe so much in my firepower."
Justin Gaethje: "I'm going to be perfect for 25-minutes. If he can beat me, kudos to him but he's going to have to walk through hell like Khabib [Nurmagomedov] did. He's not as powerful, he doesn't have the structure, frame or explosive takedowns.
"He's going to have to find me by making a mistake, overreaching and getting into a grappling situation. Outside of that he better he praying that he gets to me the ground. If not, it's going to be the same night as [Michael] Chandler but five rounds."
