Watch shocking moment MMA fighters start trading blows BEFORE opening bell as chaotic bout is cancelled

AN MMA bout failed to make it to the opening bell as one of the fighters sparked a mass brawl during the introductions.

Artur Kulinskiy was set to throw down with Farid Yadullaev on Hardcore Fighting Championship's Reality Final card in Moscow, Russia, on Thursday.

But Kulinskiy, nicknamed, 'ACAB' wasn't in the mood for waiting for the opening bell.

He sensationally ATTACKED social media sensation Yadullaev as the announcer introduced the pair.

Kulinskiy ran straight towards Yadullaev and threw a wild right hand and a follow-up hook.

Yadullaev, however, managed to evade the attempted cheap shots.

But he ended up being floored by a left body kick as he retreated.

The referee tried his best to stop Kulinskiy but was unable to until security stormed the cage and separated the pair.

Footage of the insane moment went viral and stunned MMA fans worldwide.

One wrote on Instagram: "What was necessary to prove?"

Another said: "F*** this is the best thing I've ever seen on hardcore."

And another said: "Are you serious?!"

One remarked: "F*** hype fighting."

Another simply chimed in: "Circus."

Hardcore chiefs immediately cancelled the bout, much to the frustration of Yadullaev.

The Moscow influencer commented on a clip of the video and said: "Well, Akab is draining the fight, now I'm waiting for him to continue.

"But he's not there, and what do you say?

"I'm still in the arena, Akab, if you're a man, come out.

"I'm dressed and standing near the cage!!!!"
