There's something extra vicious about a heavyweight head kick knockout.

Whether it's the sound when the kick connects or the thudding bounce of the unconscious big body on the canvas, there's nothing quite like a head kick KO at the 265-pound weight limit.

At Tuff-N-Uff 143, O'Shay Jordan (3-2) smashed Mark Currier (3-6) with a powerful left head kick in the third round of their heavyweight tilt at Palms Casino in Las Vegas. Currier immediately stiffened and crashed to the mat, creating a loud thump like a professional wrestler bumping in the ring. Only this wasn't a scripted fall, and the hammerfists that rained in from Jordan until the referee rushed in were brutal, too.

After the referee saved Currier from further damage, Jordan immediately went into celebration mode, and nearly scored another knockout as he narrowly missed connecting with another head kick to a commission official who entered the cage.
