Fighter wins UFC contract with sickening head kick KO

MMA fighter Julian Marquez has earned himself a spot on the UFC roster with one of the most awful-sounding knockouts you'll ever hear.

Marquez was taking part in the UFC Contender Series on Wednesday when he floored Phil Hawes with a massive head kick.

The Contender Series was set up by UFC boss Dana White to unearth talented fighters, and this one certainly did the trick.

Marquez hit Hawes with a series of punches, forcing him to retreat to the side of the octagon.

With his opponent hunched over, Marquez then produced a brutal kick to the head that made a truly sickening 'crack' when it connected.

The crowd immediately erupted as the referee was forced to stop the fight, and White couldn't believe what he'd seen from his ring-side seat.

The UFC boss later offered Marquez a contract to fight in his promotion.

"I didn't fight for Dana White. I fought for myself," Maruqez said after the fight.

Irishman Sean O'Malley recently won himself a UFC contract in similar fashion.
