Charles Oliveira takes on Dustin Poirier in the headline event at UFC 269 this weekend.
The annual end of year card is usually one of the more loaded cards of the year and Saturday night's show is no different.
Two champions are set to defend their belts, upcoming stars getting their chance to shine on the big stage and legends of the sport looking to write new chapters of their legacies.
Former opponent of Conor McGregor, the ex-lightweight champion Poirier will look to regain his title against current champion Oliveira.
And the co-main event will see two-division champion Amanda Nunes return to defend her bantamweight crown for the first time since 2019.
It has been an incredible year for the UFC, with the sport growing in popularity across the globe.
It's been a big year for British fighters in the company too, with Leon Edwards claiming a huge victory over Nate Diaz, Tom Aspinall continuing his perfect record since joining, and Liverpudlian Paddy Pimblett announcing his arrival with a statement round one knockout.
