Watch stunning SIX SECOND knockout in brutal bare-knuckle boxing fight leaving UFC legend Conor McGregor in awe
CONOR McGREGOR was left in awe following a SIX SECOND bare-knuckle boxing knockout.
McGregor - famed for his legendary KOs in the UFC octagon - is now a part-owner of Bare Knuckle Fighting Championship.
He is regularly promoting BKFC events and highlighting their biggest moments.
And there was potentially not a more sensational moment than Ruben Warr's six second KO of Robbie Peralta.
Peralta - formerly of the UFC - rushes towards Warr but he is met with a two-punch combination.
The resulting right hand dropped Peralta immediately to the canvas.
McGregor, 35, posted the KO and captioned it: "6 Second KO in our
@bareknucklefc main event last night!
"Our combatants do not start in the traditional red and blue corners before the bell rings they stand right in front of each other in the center of the ring!
"Behind enemy line, accuracy is final!"
McGregor was not the only one shocked as one fan said: "Oh wow f***ing hell."

Another added: "Holy f***ing smokes."
McGregor teamed up with BKFC boss David Feldman to help promote the company - with a shock bare-knuckle debut not ruled out.
The Irishman is currently nursing a toe injury that forced him out of his UFC return against Michael Chandler, 38, on June 29.
A rescheduled date is yet to be confirmed as father-of-four-McGregor took a family holiday to Majorca with fiancee Dee Devlin.
