Just this past Friday (Aug. 31, 2012), Andrei Arlovski and Tim Sylvia battled it out for the fourth time inside a cage at ONE FC 5: "Pride of a Nation" in Manila, Philippines. "The Pitbull" vowed to get his revenge on "dickface," no matter the cost, and that's exactly what he did.

The cost ended up being the fight.

The Belarusian dropped "The Maine-iac" with two powerful right hands and then proceeded to kick the big man in his head while he was down (watch the .gif by clicking here). The problem, of course, is that he didn't get permission from the referee first, which one has to do in ONE FC in order to execute a soccer kick.

Arlovski was given a yellow card while Sylvia was given five minutes to recover. He couldn't, and the bout was called a no contest, planting the seeds for a fifth meeting between the eternal rivals.

If they do meet again and it goes the same way, it will be a clean win for Arlovski.

That's because the promotion announced that going forward, it will adopt PRIDE rules in regards to soccer kicks. From the organization's Twitter:

Effective immediately, ONE FC has adopted full PRIDE rules for soccer kicks. Catch ONE FC: Rise of Kings on Oct 6!

And now it's open season.
