There have been some fantastic knockout videos cropping up recently, but this one is probably the best of the year so far.
It dates from the UCMMA - formerly Cage Rage - event that took place on May 26 in London between Galore Bosando and Wendle Lewis.
Bosando seems to have a background in karate or Tae Kwon Do - possibly both - and he also has serious flexibility, which allows him to generate serious power with the spectacular fight-ending kick that comes at 10:25 of this video… (the whole fight is worth watching though)
