Khabib Nurmagomedov has issued a stern warning to Conor McGregor, should the Irishman turn up at UFC 242 in Abu Dhabi.
The undefeated Russian phenom is set to defend his UFC lightweight title against Dustin Poirier at UFC 242 in September, and McGregor could be in the house.
Dana White thinks McGregor could show-up and ahead of a potential appearance, Nurmagomedov has said his "shenanigans won't work" in Abu Dhabi.
"It will be more difficult to leave Abu Dhabi than New York," he said.
"If he plans to come, he should sit and watch the fights because it will be impossible to pull any of his underhanded tricks there.
"Abu Dhabi is no place for show-offs. Let him come if he plans to come, but his shenanigans won't work there."
The last time McGregor was present for a Nurmagomedov fight was back at UFC 223 during fight week in April 2018, where the former 'champ-champ' attacked a bus carrying fighters.
A rematch between Nurmagomedov and McGregor continues to be mooted but the UFC king is more concerned with facing top contender Tony Ferguson.
"Of course, we need to fight with (Tony) Ferguson. But I don't choose my opponents and never choose," he said.
"Tony wants to fight, he must take the initiative. I don't care if Ferguson is put in place of Poirier or someone else. I will fight anyone.
"Definitely, my career is not at the initial stage," the 27-0 fighter added. "I am somewhere near the end. But I probably need to hold a couple of fights. I feel that there is still a rivalry in me.
"I want to play, I want to compete with the best fighters in the world. We'll see This is a question that is now meaningless to answer - I have a fight ahead."
