Conor McGregor's much-anticipated UFC 303 comeback fight against Michael Chandler has been postponed due to a broken toe sustained during a training session. McGregor explained that a lapse in concentration led to the injury, which requires a few weeks to heal, and shared photos of his injury on social media to quell doubts. UFC President Dana White confirmed the fight's cancellation after McGregor's Dublin press conference was abruptly called off. The MMA community has had mixed reactions, with some fighters mocking McGregor while others, like Dillon Danis and sports doctor Brian Sutterer, defended his decision to withdraw. McGregor remains optimistic about his return, aiming to be at 100% for his next bout, whether against Chandler or another opponent.
