Pitbull, an MMA fighter, knocked out his opponent so quickly that the clock didn't even appear on the screen.

At a KSW MMA event on Saturday, Bogdan Gnidko achieved a five-second finish.

He now belongs to the fabled five-second KO club alongside Jorge Masvidal. But Uly Diaz beats them both.

Bogdan Gnidko, a light heavyweight from Ukraine, participated in his eighth professional match at the KSW 73 nine-bout programme held at Cos Torwar in Warsaw, Poland.

Piwowarczyk was trying to uncork a kick of his own when it hit him; however, he quickly got free.
