This is 19-year-old Conor McGregor’s first ever knock-out in MMA (Video)

Conor McGregor has a gift for knocking people out.

The featherweight UFC champion proved this with deadly effect in seconds against pound-for-pound king Jose Aldo at UFC 194. The Notorious proved it the time he sparked out Mike Wood in 16 seconds back in 2011...then went one better the following fight when he put Paddy Doherty's lights out in just four seconds with an eerily similar shot to the one that put Aldo to sleep. The man has been doing it all his life. Nearly 90% of the time, it works every time - with 17 of his 19 wins coming by way of KO or TKO. Even back when he was a teenager it seems very few people could take the shots he was dishing out. JOE dug out a video of McGregor's first amateur fight when he was just 19 years old against Ciaran Campbell in 2007. His face was more boyish, his frame more wirey and his shots a bit wilder - but the result was very much the same. It wasn't quite 13 seconds, but those thunderous Irish fists ensured it didn't go past the first round... https://www.youtube.com/watch?v=fVxZNZ6ON6U Clip via Kenneth G
