When it comes to MMA knockouts, they usually consist of a brutal punch or kick to the head. Well, check out this technical knockout that took place at the Moscow MMA Open Cup semifinal on Dec. 1, 2013. Watch as the fighter in the white trunks lands a devastating back heel kick into his opponents stomach. The fighter in the blue trunks goes down immediately writhing in pain. OUCH!
