It was revealed back in February that McGregor had been the most tested UFC fighter of 2024 so far after the organisation severed ties with the United States Anti-Doping Agency last year following a public row over The Notorious’ proposed return.

The UFC’s partnership with Drug Free Sport began on January 1 and they have been regularly testing McGregor.

And the former two-weight world champion shared the latest of those tests in one of a series of photos on Instagram.

McGregor posted a number of pictures of him hitting pads and stretching in the octagon.

But one showed a drug testing kit, while another saw him getting a haircut.

And he added the short caption: “Ten rounds in the 18oz. Drug tested. Hair cut.”

McGregor hasn’t set foot inside the octagon since breaking his leg in July 2021 during a second successive defeat at the hands of Dustin Poirier.

The Irishman shattered his left tibia and fibula in the closing moments of the first round of his Sin City showdown with Poirier.

McGregor’s comeback clash with Chandler was expected to take place late last year but ultimately didn’t come to fruition.

UFC President and CEO Dana White, who announced the fight at a press conference last weekend, said of the delay: “It’s all about timing.

“Chandler’s has been ready. We talked about this at one of the press conferences recently.

“He had a lot of obligations that he had to deal with.

“What you don’t want him doing is accepting the fight when he has a ton of obligations and he can’t train 100 per cent for the fight.”

McGregor has vowed to deliver the “greatest comeback of all time” in his clash with Chandler.

And White believes it’ll be an almighty achievement for the Irishman if he has his hand raised after his injury-enforced lay-off.

The 54-year-old said: “I think when you look at that injury, it’s happened in the UFC [before].

“We just saw Chris Weidman come back, Anderson [Silva] came back; you’ve seen it in football.

“It’s probably one of the nastiest injuries you could possibly get.

“You see guys with broken arms all the time and stuff like that happens.

“It’s hard for us humans to wrap our brain around that bone breaking.”
