Conor McGregor has vowed to return to his best after the postponement of his comeback fight against Michael Chandler in Las Vegas because of injury.

The 35-year-old Irishman, who has been out of action since breaking his leg during a July 2021 defeat to lightweight rival Dustin Poirier, was due to top the bill at UFC 303 on June 29.

However, it was announced earlier this week that he had been forced to withdraw as a result of an unspecified problem.

McGregor said in a post on his official Instagram account: “Very tough to be ruled out of my scheduled return bout.

“I picked up an injury prior to the press conference that required more time to heal than was available to me. The decision to postpone the fight was not made lightly, but one made in consultation with my doctors, the UFC, and my team.

“My fans and opponent deserve me at my best for this fight and we will get there! Thank you for the messages of support, I am in good spirits and confident I’ll be back!”
