Conor McGregor brutally floored a partygoer with two punches at the infamous Pacha nightclub in Ibiza on Tuesday morning.
The disgraced fighter was seen hitting the reveller on the Spanish party island as he boozed until the early hours.
The 36-year-old was in conversation with a man before putting his arm around his shoulders and lashing out on the dance floor at 5:53 am as music continues to loudly blare.
He speaks to the man for a few seconds before hitting him with his left hand while holding a glass of alcohol in his right.
McGregor, a former UFC featherweight and lightweight champion, then lands another blow just seconds later to leave the reveller on the floor.
The Irishman, who was wearing tight white pants and a black and white shirt, has not fought since 2021 and is protected from his victim by his entourage after flooring him.
McGregor was then reportedly allowed to continue partying while the man he punched was booted out of the venue.
One party-goer told The Sun: 'Clearly something's been said to annoy him and he's reacted very badly.
'The guy seemed to fall to the floor, and his mates came to pick him up and get him away.
'There [didn't appear to be any] consequences for Conor, but the guy he punched was taken away and I didn't see him again.'
The violent scrap came just hours after McGregor was seen partying with Katie Price at Wayne Lineker's famous O Beach club.
McGregor sported red shorts, a cap, and sunglasses while puffing on a cigar and playing up to the crowds at a wild daytime party.
Price shared a picture of the pair on her Instagram page with the caption: 'You legend,' after McGregor tagged her in his own story and said: 'Forever'.
Tottenham defender Kevin Danso also posted a picture with the former fighter on his Instagram.
