McGregor is expected to fight Michael Chandler in his UFC return next year – but he is ready for just about anyone.

He posted on X: “I promise the ufc would never even have announce to me who I am fighting, they could do a surprise announcement out of nowhere, a date, an opponent, completely out of the blue, absolutely anyone, at any time, and I’d be in the gym prepping tactics for it. This is legally binding.”

McGregor, 35, has had a frustrating time on the sidelines since breaking his leg in July 2021 against Dustin Poirier, 34.

In the period out, he left the UFC’s all-year round random drug testing but has since re-entered.

Now McGregor must complete six months of clean testing before he is eligible to fight again.

And UFC president Dana White appeared to suggest the former two-weight champion is heading for a summer comeback.

He told Adam Glyn: “He’s good, he’s ready. He wants to [fight].

“He’s got to sit out for the six months to get back into the drug-testing pool. So, realistically, could be looking at him next summer.”

That could frustrate McGregor, who was hoping to fight 37-year-old American Chandler by April.

He said in Saudi Arabia: “I’m happy with April.

“I would’ve loved it earlier, but if I’m to be honest and be realistic, for my fans, I want to put in a good run, build myself back, and that’s it.

“It’s looking like April, mixed martial arts.”
