This is one of the most brutal head kick knockouts you'll ever see -- courtesy of combat sports star Superbon Banchamek -- who starched opponent Giorgio Petrosyan with a perfectly placed strike, to win the ONE Championship title.
31-year-old, #2 ranked Superbon fought 35-year-old, #1 ranked Petrosyan Friday in Singapore for the inaugural ONE Championship Featherweight Kickboxing Championship.
The knockout happened in the 2nd round of a scheduled 5-round fight ... with 2:35 minutes remaining.
Just beating Petrosyan, one of the best kickboxers in the world, is an awesome accomplishment .
