Khabib Nurmagomedov returns to the UFC for the first time since his win over Conor McGregor when he defends his lightweight title against Dustin Poirier.
The Russian submitted the Dubliner in the fourth round last October but was forced on to the sidelines when he was banned for his part in the brawl that followed his victory.
In the meantime, Poirier won the 'interim' lightweight title by beating featherweight champion Max Holloway to set up a shot at the full champion.

Latest news
Khabib Nurmagomedov has told Conor McGregor to notch up a 10-fight win streak before he can earn a rematch.
The bitter rivals clashed last October when Nurmagomedov retained his UFC lightweight title by fourth-round submission.
They then became embroiled in a post-fight brawl which landed both fighters with fines and suspensions.
McGregor has not fought since having been caught up in several legal controversies while Nurmagomedov will defend his belt against Dustin Poirier at UFC 242 next weekend.
And the Russian is in no mood to offer the former champion a second shot.
"This guy has to come back and make nine or 10-fight win streak, then we gonna fight," he told ESPN.
"Maybe people who watch this interview, they think, 'Oh, he thinks this, but when the UFC asks this guy to fight Conor for millions of dollars, this guy is gonna take it.' No; fight, come back and show who you are.
"I want to fight real guys - Dustin Poirier, Tony Ferguson, maybe if one of the greatest athletes ever, Georges St-Pierre, wants to fight. I want to fight those guys. I don't want to fight with a guy who never wins."
