UFC on Versus 6 results: Anthony Johnson knocks out Charlie Brenneman with a head kick

The second main card bout at UFC on Versus 6: "Cruz vs. Johnson" tonight (Sat., Oct. 1, 2011) at the Verizon Center in Washington D.C. featured a welterweight war with a spot among the division elite on the line.

No, the names Anthony Johnson and Charlie Brenneman may not wow you but they were both threatening a run to the top of the division heading into tonight's showdown.

Who took the next step in their quest for the 170-pound title?

That would be Johnson, who said beforehand that he would knock Brenneman out with a head kick and that's exactly what he did.

When two wrestlers meet inside the Octagon you can usually count on 15-minutes of lull or a stand up showdown with plenty of action.

In this one, we got a bit of both.

Johnson opened with his usual burst of speed and athleticism looking to land early and often with a head kick that he knew would be available to him.

Sure enough, after a brief stint battling on the floor, "Rumble" executed a swift kick to "The Spaniard's" skull that sent him flying back. Referee Mario Yamasaki quickly stepped in to stop the fight but was it warranted?

Brenneman appeared to be out but very briefly and he even landed on his elbows looking as though he could defend against any coming onslaught of follow up punches.

It didn't matter.

Did the ref make the right call or should he have let the action go a bit more?
