An MMA fighter in Poland who took a boxing match was disqualified Saturday after he knocked out his opponent with brutal ground-and-pound. The six-round bout between Marcin Sianos and Artur Bizewski took place at Rocky Boxing Night in Koszalin. Midway through Round 2, Sianos, an 8-7 MMA fighter making his boxing debut, stunned his 9-0 opponent. But rather than continue punching, Sianos tied up Bizewski with a double leg and dropped him to the canvas. From there, Sianos moved to full mount and devastated Bizewski with two massive elbows, much to the surprise of onlookers
