13 seconds is all it took, as Conor McGregor became the Undisputed UFC Featherweight Champion beating Jose Aldo at UFC 194.

The Notorious won the fight with a devastating one punch knockout as the Dubliner recorded one of the quickest finishes in the history of the UFC.

Post fight, McGregor said in the octagon that "nobody can take that left hand shot." "Precision beats power and timing beats speed", he told Joe Rogan.

Aldo's loss is his first in ten years and the Brazilian was visibly emotional after the fight. Through his translator he said that he wanted a rematch. He added that McGregor's mind games didn't affect him in the buildup to the fight.

Earlier in the night, Luke Rockhold defeated Chris Weidman to win the UFC Middleweight Champion. Rockhold defeated the previously undefeated Weidman in the fourth round.

Despite McGregor's win it was not a perfect night for Dublin's SBG. Gunnar Nelson suffered his second defeat as a professional with a convincing loss to Brazilian legend Demian Maia.
