Walt Harris handed Aleksei Oleinik a nasty knockout in just 12 seconds tonight at UFC On ESPN 4.
Punches being thrown early here. Then Harris jumps into a flying knee and then it’s a left hand to the temple behind it that brutally knocks Oleinik out cold.
Oleinik is then pictured still unconscious and shaking on the mat as Harris celebrates and then goes over to briefly check on his opponent.
The knockout finish came just 12 seconds into the fight and goes down as the third fastest finish in heavyweight history.
Afterwards Oleinik is seen back up on his feet and walking very slowly out of the Octagon helped by his cornermen, with the suggestion being that he may have also suffered a leg injury as he fell to the mat from that thunderous blow.
