GETTY Conor McGregor, UFC lightweight champion

Just moments ago, the UFC’s lightweight champion stormed the venue for UFC 223 with his posse after the media day for the fourth pay-per-view card of the year had ended. And according to multiple reporters on the scene, the UFC lightweight champion and his entourage proceeded to go wild. A few minutes ago, ESPN’s Brett Okamoto claimed that McGregor and his team ‘swarmed’ a bus with fighters leaving the venue. He tweeted: “Conor McGregor stormed through Barclays, ended up in the loading dock of the arena with his entourage in tow and “swarmed” a bus that was leaving with UFC fighters and camps. “Conor and crew were “throwing chairs, bike racks."

MMAFighting’s Ariel Helwani tweeted: “Conor McGregor and members of his team showed up at the Barclays Center at the very end of media day moments ago. “There was an altercation with some of the departing fighters who are competing on the card. “I’m told as the van was driving away to take the fighters back to the hotel that’s when it happened. Those fighters haven’t left the arena now.

“I’m told that chairs were thrown through the van window and one passenger on the van was injured. “Dana White is on his way back to the arena. Most of he fighters are still in the arena but some were able to leave.” Helwani then went on to reveal that UFC lightweight Michael Chiesa, who is set to take on Anthony Pettis, suffered a cut as a result of the melee. He added: “According to multiple sources Michael Chiesa suffered a laceration in the fracas.

“He is being attended to at the arena. Unclear at this time how serious his injury is.” Chiesa’s coach Rick Little confirmed the injury, telling MMA Junkie: “Conor went bananas and put a beating on the van that we were in looking for Khabib. “A million security guards had to restrain him. Mike’s cut up now. “He’s got marks on him, for sure. I don’t think too serious. Everything happened so fast, it was just like we got jumped.”

According to Helwani, McGregor was attempting to get Khabib Nurmagomedov out of the van. If true, it seems that McGregor was attempting to get his hands on Nurmagomedov following the emergence of footage of the Dagestan native confronting 'The Notorious'' team-mate Artem Lobov. “I’ve seen video shot by fighters in the van,” Helwani said. “Very clear Conor is telling someone to get out of the van before being pulled away by security. “Khabib and his team were in that particular van."
