Conor McGregor ‘s homecoming was ruined just seconds into the fight when he landed wrong, damaging his leg, rendering himself unable to continue moments after the opening bell in the UFC 329 headliner. The long layoff and subsequent injury led many to call for the Irishman’s retirement from the sport. Instead of laying down his gloves and moving on from a career that brought much success, ‘The Notorious’ is determined to fight his way back to full fitness and give the story of the greatest comeback in sports history a second chapter.
