The UFC is set to start the year with a bang, with several big fights already announced, including the interim lightweight title clash between Justin Gaethje and Paddy Pimblett in Las Vegas.
The bout will headline UFC 324 on Jan. 24 at T-Mobile Arena.
Pimblett (23-3) told ESPN last month he still wants an undisputed fight against lightweight champion Ilia Topuria (17-0), who is taking time away from the cage for personal reasons.
However, the Liverpool fighter insisted he is taking nothing for granted against Gaethje (26-5) in what promises to be an engrossing battle.
The undercard features several interesting match-ups, but women's bantamweight champion Kayla Harrison vs. Amanda Nunes has been postponed.
Former men's bantamweight champion Sean O'Malley will return to the Octagon against Song Yadong.
Here is everything you need to know ahead of the fight.

When is the fight?
UFC 324 will take place on Jan. 24 at the T-Mobile Arena in Las Vegas.
The main card is set to start at 2 a.m. on Sunday Jan. 25 in the UK (9 p.m. ET).
Prelims are set to begin at midnight UK time or 7 p.m. ET.
Where will the fight be broadcast?
Pimblett vs. Gaethje will be on TNT Sports Box Office in the UK. The price is £19.99 on discovery+, EE TV, Prime Video, Sky and Virgin Media TV
The card will also be the first under the UFC's new broadcast deal with Paramount+ in the United States.
ESPN will have live updates of the card throughout fight night.
What is at stake?
The main event will be for the UFC interim lightweight championship, with the winner set to be next in line for a shot at Topuria, or fight someone else for the undisputed title at 155 pounds.
While Pimblett is ranked No. 5 in the division, he is one of the biggest rising starts in the sport with recent wins over Tony Ferguson and Michael Chandler propelling him up the division.
He has also done a good job of promoting himself, with a high-profile rivalry with Topuria.
Meanwhile, Gaethje is looking to re-claim the interim title he won against Tony Ferguson in 2020 and go for potentially one last shot at the full title.
