The former two-division champion at featherweight and lightweight was originally scheduled to return against Michael Chandler at UFC 303 in June 2024 to conclude their Ultimate Fighter 31 rivalry, after the show aired in 2023. However, a McGregor toe injury forced a postponement and the match was never rescheduled.
McGregor, 37, returns to the welterweight division for the first time in six years.

Holloway (27-9 MMA) is making his official welterweight debut after a historic run at 145lb (65.5kg) and 155lb (70.5kg) over the last decade-plus.

What have McGregor and Holloway said?
McGregor said he is grateful for the opportunity to reinvigorate his career and has no immediate plans to change weight divisions after the Holloway rematch.
“The OG champ-champ, coming for the triple crown,” McGregor told reporters at Thursday’s pre-fight news conference. “Sounds like a hell of a story to me.”
Following the loss of his “BMF” title to former lightweight champion Charles Oliveira at UFC 326 in March, Holloway, 34, hopes to avenge the loss to McGregor and immediately enter the 170-pound (77kg) title picture should he opt not to return to lightweight.
“We’re gonna find out Saturday night,” Holloway said in response to McGregor’s claim that he won’t “lay a glove” on him.
McGregor said he was not pleased with Holloway’s “disrespectful” comments about offering a potential December rematch, ensuring it will not be needed.
In response, Holloway fired back, igniting the rivalry even further.
“I’m drowning his a**,” Holloway said.
What happened in the first McGregor vs Holloway fight?
McGregor defeated Holloway via unanimous decision (30-27, 30-27, 30-26) on August 17, 2013 at UFC Fight Night 26 in Boston.
The fight took place before they became global stars and was on the preliminary card that evening.
McGregor’s striking proved to be a problem for Holloway early in the fight, and he wobbled the Hawaiian with a big uppercut in the second round. But the second half of the fight mostly took place on the ground, with McGregor enjoying enough control to see out the win.
The Irishman suffered an injured ACL during the fight and later required surgery, which kept him out of action for 11 months.
