McGregor released a photo on his Instagram account showing his left thumb wrapped in a cast with his hand and arm also wrapped up with bandages.
While he didn’t detail the extent of the injury, McGregor is anxiously awaiting the cast to come off so he can get back to work in the gym.
“Intense training and sparring sessions, I will always push it to the limits,” McGregor wrote. “This comes off and I push on! The Proper Don! Nothing will stop me.”
