CONOR McGREGOR swigged his Proper 12 whiskey from the bottle as he made a shock appearance at a bare-knuckle boxing event.
The Irishman took a ringside seat in Denver to watch former opponents Chad Mendes and Eddie Alvarez put on a brutal show.

Alvarez, 39, beat Mendes, 37, on points before Mike Perry stopped ex-UFC champion Luke Rockhold in two rounds of the main event.
And McGregor, 34, looked to be enjoying himself as he was captured sipping his limited edition Irish Apple whiskey.
But it left some fans fearing the worst with the MMA legend, who is set to make his UFC return later this year against Michael Chandler, 36.
One said: “There is no way this dude is fighting Chandler.”
Another added: “Conor training that liver.”
One commented: “This dude ain’t fighting.”
Another agreed: “I don’t think he’s fighting Chandler.”
McGregor was later called out for a face-off with Perry, 31, and opened the door to a bare-knuckle boxing switch.
He said: “Fair play to you mate, I respect you. I’m into this game, I’m into this game.
“Fair play to you. I’d fight you. I’d fight you most definitely. I’d fight you no problem, mate. I’m never retiring.”
Perry said in his post-fight press conference: “What’s next for me? Conor McGregor.
“He likes to box too, we can go throw hands. And he gave me a face-off, man. How cool was that?”
