White, chief of UFC, says Chiesa was drunk after trying to enter the octagon with Pena to celebrate her win.

UFC fighter Michael Chiesa got so drunk at UFC 269 that he tried to enter the octagon by breaking his eye.

This is the claim of Dana White, franchise chief. She revealed that Chiesa was thrown while celebrating Julianna Pena’s victory over Amanda Nunes.

Chiesa, Welterweight, was in Las Vegas to help Pena. He got a bit carried away when Pena pulled off one the greatest upsets in UFC history.

After an altercation with security personnel and police, the 34-year-old was taken out of the T-Mobile arena.

White stated: "How can I say it without embarrassing the man...

"He had a little too much to drink this night.

"When she won the contest, he was scared and tried to jump in the octagon.

"He fell on his face and cut his eye, then he ripped his eye open.

"Then, he was arguing to the police that he needed the octagon for his team-mate and that he should be there with her.

"[The police] pulled him out and got him outside. They then calmed him in the back.

"I talked to him for a while, and now we're all fine."

Both Chiesa, Pena and others train from Sikjitsu in Spokane Washington.

After Nunes' reign ended as UFC bantamweight champion, video footage shows Nunes launching himself across the barrier from his front row seat.

In the co-main event, the pound-for-pound queen was defeated by the Venezuelan Vixen in a shocking second round submission.

Nunes' six-year unbeaten streak in Ultimate Fighter 18 was ended by the defeat of former Ultimate Fighter winner.

Pena, who was elated after the fight, told Joe Rogan, UFC commentator, "I'm surprised, motherf r."
