Conor McGregor's late arrival led to Khabib Nurmagomedov carrying out his own press conference ahead of the pair's showdown at UFC 229.

The UFC lightweight champion turned up promptly at 3pm on Thursday at Park Theater in Las Vegas and completed his media duties before McGregor's arrival.

The Irishman would later blame his tardiness on the Las Vegas traffic but Nurmagomedov was uninterested in hanging around, depriving those in attendance the chance to see the interaction and a face-off between the pair.

He said: "I don't need to wait for nobody. This is 3pm, the fans are here, media are here, everybody is here.

"If somebody is late, this is not my problem. I don't think about him.

"I have a schedule, 3pm I am here. I have to make weight and worry about myself." 

The Dubliner eventually did arrive, after Khabib had left, and he predicted he would make up to $50m from the showdown.

"They’re estimating around 3 to 3.5 million [PPV buys]," said McGregor.

"I’d say I’m closing around the $50m mark. For a mixed martial artist to make $50m for a mixed martial arts bout, it’s quite breathtaking."
