CONOR MCGREGOR has been gearing up for his UFC return with a bare-knuckle training session.
The MMA superstar is in the final stages of recovering from the horrific broken leg he suffered in his trilogy fight with Dustin Poirier last July.
McGregor, 34, has been hard at work in the gym over the last two months – regularly hitting the heavy bag and pads.
And one of the Irishman's recent workouts saw him nail the heavy bag without any gloves or hand wraps.
The Notorious shared a clip of himself unloading shots onto the bag to Instagram early on Saturday morning.
The video showed the UFC's poster boy measuring the bag with straight lefts and throwing looping right hooks.

One remarked: "Can't wait for your return champ champ."
Another chimed in: "Come on McGregor show everyone what you can do.
"So many lost fights and I still believe in you. May the gods bless you."
Former two-division champion McGregor began kicking with his injured leg late last month and has since resumed mixed martial arts training.
And head coach John Kavanagh was thoroughly impressed by what he saw of the Dubliner in his return to Straight Blast Gym Ireland.
He told The BBC: "He's healthy, happy and it's great to have him back.
"The last few sessions in the gym here were MMA-orientated – he's got the all-clear for that now.
"He did a great session last night, we got some great rounds in. He hasn't lost a beat and was looking great.
