Khabib Nurmagomedov and Conor McGregor will both be spoken to following their controversial social media exchange.
McGregor posted a picture of Nurmagomedov and his wife, accompanied with the words: "Your wife is a towel mate" before swiftly deleting the post.
Nurmagomedov returned fire by calling McGregor a 'rapist'.
"Rapist, you are Rapist. You are a hypocrite who is not responsible for your actions. Justice will find you. We will see."
The situation has escalated to the point where UFC president Dana White is set to reach out to both fighters.
"I am aware of the recent social media exchange between Khabib Nurmagomedov and Conor McGregor," he said.
"The ongoing situation has escalated to a level that is unacceptable. As such, we are taking the necessary steps to reach out to both athlete camps and this situation is being addressed by all parties internally."
White stepping in is the right call. The situation is clearly getting out of hand and needs controlling.
Meanwhile, Nurmagomedov is currently serving a nine-month suspension for his actions during the post-fight brawl which marred UFC 229.
But he's expected to return to the famed Octagon in September. White has confirmed Nurmagomedov will be back in action in September.
"He'll be back in September," he said. "It's one of the things with him anyways, he's on suspension and then he doesn't fight during Ramadan. That puts him at September."
What's more, it appears a September 7 date is in the works.
McGregor, of course, called time on his MMA career after posting a retirement message on Twitter.
"Hey guys quick announcement, I've decided to retire from the sport formally known as 'Mixed Martial Art' today. I wish all my old colleagues well going forward in competition," he said.
"I now join my former partners on this venture, already in retirement. Proper Pina Coladas on me fellas!"
