This is the 4-second Conor McGregor knock-out he executed with the exact same punch he KO’d Jose Aldo with (Video)

Conor McGregor's 13-second knockout of Jose Aldo was the quickest in UFC title fight history.

The one-punch KO stunned the MMA world the moment his short left hook landed on the jaw of the Brazilian. But the only person who wasn't surprised by the ruthless speed in which he floored the man who had not been beaten for 10 years was McGregor himself. The Dubliner predicted he would score a first round KO, he predicted the sequence that would end the fight and he was even filmed practising that very shot in the changing rooms before the UFC 194 main event. When asked if this  knockout was a flash in the pan - McGregor calmly told journalists that he had others to his name - a 16-second KO and even one inside just four seconds. But it was this four-second knock-out against Patrick Doherty in the Immortal Fighting Championship in Ireland in 2011 that really stands out. It is pretty much the exact shot that brought down the UFC's pound-for-pound king... https://youtu.be/awSGWLpZ-LE Clip via Gangs of Immortal Europe
