Conor McGregor shows off insane body transformation in boxing workout ahead of UFC star’s long-awaited return

CONOR MCGREGOR looks to be in prime condition as he gears up for his return to the UFC.

The MMA superstar has packed on several pounds of muscle during his recovery from the horrific broken leg he suffered last July.

And he looked to be in great condition in an Instagram post this year showing him drilling a heavy bag at Crumlin Boxing Gym in Dublin.

The Irishman's back and arm muscles bulged at the seams as he practised overhand rights and right hooks.

But UFC fans were more interested in his accompanying caption than the pictures themselves.

It read: "Right hook tastiness. Catch you soon, the countdown is on."

McGregor's legion of followers flocked to the comments section, with one saying: "The new season."

Another said: "Let's f****** go. Come back like Rocky did."

And another said: "Let's go, king!! Show them what's what!!"

One remarked: "Can't wait to see you back in the ring champ."

Another chimed in: "Soon there will be a crushing knockout from Conor."

McGregor is in the final stages of recovering from the broken leg he suffered in his trilogy fight with former interim lightweight champion Dustin Poirier.

The Dubliner was eyeing a summer return to the octagon, although UFC president Dana White said autumn is a more realistic timeframe.

He told SunSport: "We're looking at early fall, if everything goes right."

The autumn timeline for McGregor's return is dependent on his leg being completely healed and doctors giving him the all-clear.

White added: "If his leg heals right and he gets the clearance to really start training, then possibly early fall.

"We'll see when he's ready to fight. And when the doctor gives him 100 per cent clearance we'll start looking at possible opponents."
