The UFC returns to our screens this weekend with the fourth pay-per-view event of the year - however, it'll be free to view for UK viewers who have a BT subscription. UFC 273 will see another stacked card including two title defences, one of the best pound-for-pound fighters in action along with two of the most exciting rising stars in the industry.
In the main event, Australian featherweight champion will hope to continue in his tremendous in his perfect 10-0 record in the UFC since joining - after registering statement victories over Brian Ortega, Jose Aldo, Chad Mendes and Max Holloway twice. The former Rugby player will defend his title against the legendary Chan Sung Jung, also known as The Korean Zombie, who gets his second shot at the title after his 2013 loss to Aldo.
Volkanovski has been involved in a number of fight of the year candidates, with his last defence against Ortega being recognised as the best in 2021, alongside Justin Gaethje's win over Michael Chandler.

Elsewhere on the card, Aljamain Sterling will defend his belt in a rematch with Petr Yan, after the latter was disqualified for an illegal knee in their last bout. Yan was undefeated in the UFC before the DQ loss, and was comfortably on top of Sterling in their last bout.
And maybe the most highly anticipated fight of the night will see the man who looks destined to become the UFC's next biggest star, Khamzat Chimeav, coming up against by far the toughest opponent of his career so far in Gilbert Burns.
