Conor McGregor is gonna be working in Vegas during UFC 200 weekend -- just not in the Octagon.
Instead, he'll be hosting a post-fight party at a massive nightclub at the Wynn Hotel ... TMZ Sports has learned.
McGregor has signed on to host an "action packed evening" at Intrigue nightclub -- with special guest DJ Konflikt.
Of course, McGregor was supposed to be FIGHTING that weekend and making $10 MILLION. Instead, he'll be slamming whiskey for a lot less.
Still, we're told there's already massive interest in the party -- and VIP tables are expected to be sold for a TON of cash.
