"The Notorious" needed just 13 seconds to get rid of the "interim" that hovered over his name since July 11.
The Irishman dethroned Jose Aldo with one solid left hand that knocked the Brazilian out cold in the main event of UFC 194.
The pair declined to touch gloves and during the first exchange, McGregor slipped the right hand of Aldo and connected with a straight left.
Aldo dropped to the canvas and McGregor finished the job with a few shots on the mat before John McCarthy waved it off, making it the fastest title fight in UFC history.
WOW!
