Conor McGregor is looking jacked as he resumes MMA training at SBG Ireland in advance of the blockbuster UFC Return

CONOR MCGREGOR appears to have resumed mixed martial art training in preparation for his eagerly-anticipated return back to the octagon.

As he is nearing a complete recovery from his horrific injury to his leg last July, the UFC's poster child has intensified his training.

McGregor, 33 years old, has been taking up boxing as his leg recovers to full strength.

The Irishman seems to have resumed MMA training, as he was spotted at Straight Blast Gym in Dublin this Thursday.

As he trained at home, The Notorious wore red UFC shorts and posed with his teammates for photos.

Darragh Kelly, a Bellator lightweight, shared a photo of McGregor and himself to Instagram. The caption was: "Looking forward for the comeback."

McGregor's new, jacked physique was a big show. One commentator said that McGregor is huge.

Another commented, "Conor is looking huge!" The next weight loss will be the most healthy we have ever seen.

Another said, "Looks heavy, look out for light/welterz."

One commented: "That's Conor...That dude ate Conor!"

Another participant said: "An animal is an animal."

McGregor, a former two-division champion, was on track to make an autumn return to cage but only just started kicking late last month.

UFC President Dana White expects the pride of Dublin will be back in action before the end of this year.

Jim Rome was asked McGregor's next fight location.

"Conor wants to return at the end this year and early next year."

He said: "Conor wants to fight when I talk to him.

"Conor receives many offers for film roles and other things that he could do to make money.

"He doesn’t want to do that." Conor is willing to fight."
