Conor McGregor trains in Celtic jersey while rumours suggest UFC will strip him of lightweight title
The 29-year-old has been warned by UFC president Dana White as he eyes a return to the octagon
CONOR MCGREGOR is hard at work in Dublin as he prepares for his UFC comeback.
'The Notorious' continued to share pictures of his training in Dublin as he donned a Celtic jersey at Straight Blast Gym.
McGregor has professed his support for the Glasgow club and paid tribute to them on social media in August when Celtic fans held up a banner with one of his famous quotes.
In October, he sang a Celtic song at an event in the Scottish city and had a drink thrown over him.
With his latest snaps shared on Instagram, Hoops full-back Kieran Tierney commented: “Nice shirt my man! Hero.”
The official Celtic account commented: "Hail, Hail @notoriousmma!"
McGregor looks determined as he prepares for his return to the octagon but reports have suggested he will be stripped of his UFC lightweight title tomorrow.
The 29-year-old has not fought in the UFC since November 2017, when he defeated Eddie Alvarez in New York to land the lightweight strap.
TIME'S UP UFC to strip Conor McGregor of lightweight title on Saturday allowing Tony Ferguson and Khabib Nurmagomedov to fight for it
Podcast host and UFC commentator Joe Rogan believes he should be stripped to allow other contenders an opportunity.
He said: "When you’re a professional athlete, time is your enemy. And we can’t go on forever and not give guys the opportunity.
"Tony (Ferguson) has been around for a long time and has earned his dues. Khabib (Nurmagomedov) has earned his dues. And the list goes on and on and on. So Conor has done very well, he’s made a lot of money.
"And if he decides if he doesn’t want to fight again for another how long, that’s up to him. That’s his choice and his decision.
"But the belt has to move on. So we’ve got to figure some stuff out here in the next couple of months."
