Tim Sylvia
Arlovski and Sylvia faced off at on 31 August 2012, in Manila. The fight between Arlovski and Tim Sylvia ended in a no-contest due to an illegal soccer kick by Arlovski. According to ONE FC rules, soccer kicks are legal only if the referee clears the fighter to do so after determining the grounded fighter can still intelligently defend himself. Arlovski received no such clearance and the kick was therefore deemed illegal. Four days later, One FC eliminated this restriction. This rule change, had it been enforced prior to the bout, would have resulted in Arlovski winning by TKO. Arlovski had knocked Tim Sylvia down with punches before he landed the illegal kicks that caused the referee to stop the fight.
