It was billed as an all-out war between two men who aren't afraid of anything, and the UFC 229 main event delivered.
Unfortunately it wasn't the outcome UFC President Dana White wanted as all hell broke loose following Conor McGregor and Khabib Nurmagomedov's championship fight.
After Nurmagomedov forced McGregor to tap out, courtesy of a rear naked choke, the Russian began unloading a verbal tirade in the direction of McGregor's corner.
As the insanity was unfolding outside of the cage, inside McGregor was swarmed by three of Nurmagomedov's teammates in what looked like a co-ordinated attack.
The moment left all watching on in utter disbelief and had White "disgusted" at the scenes which had unfolded.
Both men were escorted from the ring by security in the hopes of avoiding any further outbreaks among the crowd.
Both White and Nurmagomedov fronted the media, with the Russian fighter apologising but at the same time pointing the finger at McGregor.
"I want to say sorry … I know this is not my best side," Nurmagomedov said. "(But) he talk about my religion, he talk about my country, he talk about my father, he came to Brooklyn and he broke bus, he almost kill a couple of people."
Despite the ugly turn the fight took, it seemed to please Russian president Vladimir Putin who offered up his congratulations to his fellow countryman.
The three men who entered the cage and went after McGregor were all arrested, but later released after the Irishman refused to press charges.
After skipping out on the post fight press conferences, the world waited with bated breath for a response from the man who is just as devastating with his tongue as he is his hands.
But almost five hours after the final bell had rung, McGregor broke his silence with one simple tweet: "Good knock. Looking forward to the rematch".
An investigation into the wild scenes that unfolded at the main event are currently ongoing, with Nurmagomedov's $2 million purse for the fight being withheld.
He now also faces a nervous wait to find out just what penalties will be handed down.
"There's a lot of repercussions for what they did tonight," Dana White said.
"We have to see what happens with the Nevada State Athletic Commission — not just the commission, there's going to be fines, God knows what. Can these guys get visas and get back in the country?
"The biggest night ever and I couldn't be more disappointed ... this is some street shit going on here. This isn't sport."
The outcome of the investigation could bare huge weight on the likelihood of McGregor's tweet, but fans of the UFC would love nothing more than to see these two square off in the future.
