One report has Nurmagomedov slapping Dvalishvili to kick off the brawl, while another describes it as a jump led by Nurmagomedov with friends in tow.

Dvalishvili gave his own account of what happened. "Was doing an interview for RAF in hotel lobby and Usman and his buddies came up from behind and started punching me and my young friend. Security was holding me, they kept kicking us when we were down like losers," he said.

The fallout has been swift. MMA Fighting reported that fighters across the sport have condemned Nurmagomedov and the friends who joined him, even as he's being talked about as one of the hottest free agents in combat sports right now.

Conor McGregor has also weighed in, reacting to the attack on his friend and hinting that Ilia Topuria could be the one to settle the score, according to Bloody Elbow.

The incident lands at an awkward moment for Dvalishvili, who is still ranked number one at bantamweight despite dropping a unanimous decision to Petr Yan on October 24. Our Elo model has him at 1601 built off eight bouts, still elite territory even coming off that loss.

McGregor, for his part, hasn't fought since getting finished by Max Holloway in the first round this past July. Topuria, the man McGregor is pointing toward, remains the number one ranked lightweight with a 1600 Elo across six bouts, even though his own last outing ended in a fourth round knockout loss to Justin Gaethje in June.
