Just 13 seconds into the fight, McGregor perfectly timed a counter left hand as José Aldo rushed forward. The punch landed flush, instantly ending Aldo's decade-long unbeaten streak and crowning McGregor the undisputed UFC Featherweight Champion. In a moment that lasted only seconds, McGregor fulfilled years of bold predictions and cemented his place as one of the sport's biggest stars. #conormcgregor #UFC - @bigmomentsports3
