Two fights ago, Donald 'Cowboy' Cerrone was contemplating retirement but that idea seems like a distant memory now after a head kick knockout put away top Brazilian prospect Adriano Martins at FOX UFC Saturday.

Heading into the fight, Cerrone (22-6, 1 NC) was favored over Martins, but there was a buzz in the air that the former lightweight contender could be in for an upset while facing a much-hyped fighter out of Brazil.

Martins (25-7) stood toe-to-toe with Cerrone early and it was clear he wasn't backing down from the Denver native's aggressive attack.  Add on to that the fact that Martins is a massive lightweight, and he was ready to show his power against Cerrone.

Unfortunately for Martins he never got the chance.

With less than a minute to go in the round, Cerrone uncorked a right high kick that saw his shin land flush against Martins' neck.  The Brazilian fighter bent over and crumbled to the mat from the strike, and the referee ran in for the save to prevent any further damage from happening.

The crowd in Chicago gasped when Cerrone's leg connected with Martins, who was dazed for a few moments on the ground before eventually getting back to his feet where he congratulated his opponent.

The win will likely earn Cerrone another high-profile bout, but given his nature of asking UFC matchmaker Joe Silva for as many fights as he can book, there's no telling how soon he might just step back in the cage again.

If he's willing to wait, Cerrone could probably demand a top-ten fight, but he's never been the kind of fighter to turn down any opponent so it's anybody's guess who could be next.

One thing that's for sure after his latest win -- Cerrone, who expressed recently about his financial need to fight so often, he will go home with a win bonus and possibly a Knockout Of The Night trophy when the night is over.
