UFC 304 stars Muhammad Mokaev and Manel Kape were involved in a wild brawl at the fighters' hotel ahead of their showdown.

The UFC flyweight contender bout between Mokaev and Kape is the standout fight on the early prelims.

No.6 ranked Mokaev meets Kape, who's ranked eighth in the division, in what could determine the next challenger for UFC flyweight champion Alexandre Pantoja.

Extra spice has been added to their contest as they clashed at the fighters' hotel in an explosive moment.

A viral video shows Mokaev's team and Kape's entourage going at it in extraordinary footage.

People were restrained as security intervened.

After the melee, the 23-year-old took to social media to post an image of Kape, who appeared to suffer a cut on his face.

It's not their first run-in as Mokaev and Kape also came to blows at the UFC Performance Institute in Las Vegas, Nevada.

According to Kape's teammate, Jean Silva, the 30-year-old hit the young Brit outside the gym.

"Manel Kape hit Mokaev here outside the gym a while ago," Silva revealed.

"He elbowed Mokaev in the head on the street bro. Bro, he caught Mokaev at the entrance here to the (UFC) PI, he headbutted him and elbowed him, in the street. He opened Mokaev’s head a week before his fight. He’s (Kape) a psychopath."

Mokaev heads into his UFC 304 assignment with six UFC victories under his belt.

He's gunning for a shot at UFC gold.

Kape, on the other hand, is 4-2 in the UFC, having beaten Ode' Osbourne, Zhalgas Zhumagulov, David Dvorak and Felipe dos Santos.
