ONE Fighting Championship: Pride of a Nation
ONE Fighting Championship: Pride of the Nation took place on August 31, 2012 at the Smart Araneta Coliseum in Quezon City, Philippines. It was ONE's first event in the Philippines. ;Background Held in conjunction with the URCC, Pride of the Nation has been described as the biggest event in the history of Filipino MMA as 12,523 fans attended. The event featured three former UFC champions: Tim Sylvia, Andrei Arlovski and Jens Pulver. There were two controversial incidents at this event which involved the use of soccer kicks. Because of this, ONE will now allow their fighters to use them at any point in a fight from ONE FC: Rise of Kings. One incident was during the bout between Andrei Arlovski and Tim Sylvia. Arlovski knocked Sylvia down and then threw soccer kicks at his head. Everyone thought the referee had stopped the fight; he actually called time because he didn't call "open attack". When it was decided after a five-minute rest period for Sylvia that he could not continue, the fight resulted in a No Contest. The other incident occurred during the fight between Shannon Wiratchai and Mitch Chilson, in which Wiratchai won. However, after a thorough review of the match days after the event, ONE officials decided that Wiratchai landed an illegal leg kick to a grounded Chilson in the second round and referee Moritaka Oshiro incorrectly called an end to the fight as he determined at that point that Chilson could not properly defend himself. The win for Wiratchai was reversed and the fight officially ruled as a No Contest. ;Results
