The press conference that preceded the melee was for UFC 223 which will be at the Barclays Center this weekend.
The victor of Nurmagomedov vs Holloway will be now crowned the true 155-pound champ.
The victor of that contest will take over McGregor's belt, which has been stripped from him due to his inactivity in the sport over the last two years. He was stripped of that belt after winning the UFC lightweight title. Everything happened so fast. Well, here's a quick timeline. At the post-fight press conference, he promptly announces that he's taking some time off. The only person losing his belt on Saturday is Conor (McGregor). Once the fight starts, McGregor will no longer be champion and the need for the interim belt will go away - leaving the victor as the true 155-pound champ.
McGregor eventually found his way to a back part of the arena and a van that was hauling fighters away when a window was shattered on the vehicle, injuring Michael Chiesa and almost hitting strawweight champion Rose Namajunas, according to multiple reports.
Nurmagomedov and Ferguson have been chalked down to fight each other on five occasions but have yet to trade blows for various reasons. If Max Holloway wins Saturday night he will then become the only dual weight champion. Ferguson, still the No. 1 contender, remained in the mix.

"No interim champ. When this fight is over, champion", said White, gesturing to Nurmagomedov and Holloway.
The craziest part of all of this is that it doesn't feel surprising, at all. It marks the fourth different time that the UFC has tried, and failed, to book Ferguson vs Nurmagomedov.
Holloway, victor of 12 straight UFC fights, earned some respect from UFC fans for accepting the fight on short notice.
The fact that the UFC managed to find as exciting a replacement as Holloway feels like a minor miracle.
Though White said police had issued a warrant for McGregor's arrest and, his plane wouldn't be allowed to leave, Marc Raimondi of MMA Fighting reported that a New York Police Department spokesman said they had not issued a warrant, though they do want to speak to McGregor. I need this guy.' But Dana (said) he has to look nice - his face, everything - because now he has good sponsorships, and we can not change his face.
