Paddy Doherty was the victim. "Gone in 4 seconds". Year - 2011. This is Conor's fastest knockout ever. Since almost everybody here talks about what's next for Conor, let's get back a bit through history. Fabulous left-hand counter to end the fight, it's even quicker than the UFC's record, set by Jorge Masvidal! Note: I am not a huge fan of Conor, but this is one of the fastest knockouts ever.
