Conor McGregor is finally set to make his return to the Octagon.

Former two-division world champion McGregor (22-6 MMA, 10-4 UFC) is scheduled to face Max Holloway (27-9 MMA, 23-9 UFC) in the main event of UFC 329 at T-Mobile Arena in Las Vegas during International Fight Week on June 11, Dana White announced Saturday night.

McGregor and Holloway have fought once before, with “The Notorious” earning a unanimous decision victory at UFC Fight Night 26 in Boston back in 2013.

The fight will mark the Irishman’s first appearance since he suffered a catastrophic leg injury in the opening round of his loss to Dustin Poirier at UFC 264 in July 2021. Since defeating Eddie Alvarez to capture the lightweight title at Madison Square Garden nearly a decade ago, McGregor has competed just four times in the Octagon, losing three of those bouts.

Former featherweight champion Holloway last fought at UFC 326 in March, where he lost his BMF title to Charles Oliveira by lopsided decision. Over the past three years, the Hawaiian has competed primarily at 155 pounds, aside from his featherweight title fight loss to Ilia Topuria in October 2024.
