A UFC heavyweight delivered a devastating KO just nine seconds into fight

The UFC was in Greenville, South Carolina for the first time on Saturday in what turned out to be a pretty entertaining fight card.

Heavyweight fighter Jairzinho Rozenstruik was a big part of that entertainment as he needed just nine seconds to knock out Allen Crowder and earn a $50,000 fight bonus from the UFC.

It was the second-fastest KO in UFC heavyweight history and should push Rozenstruik up the rankings, because it was a thing of devastating beauty.

First he caught Crowder with a left that knocked him to the mat and then Rozenstruik quickly pounced and ended things with a few more brutal strikes.

Impressive.
