He made an absolute balls of that kick.
The worst illegal groin strike in the history of MMA may have happened during the second round of the bout between Wu Ze and Wu Hui Qiang at One FC.
20-year-old Ze had his opponent on his back when he tried to go in for the kill, and finish him off. After letting loose with some ground and pound, Ze grew weary oh his adversary’s resilience and tried to end the fight in spectacular fashion.
Following a soccer kick attempt, Ze launched into a parkour-style side-flip double-heel stomp that looked like it was intended for Qiang’s body. Unfortunately, it missed its mark in the worst way possible as Ze’s heels connected with Qiang’s groins with brutal power.
Somehow, after an extended resting period, Qiang was able to continue the fight and ended up losing via submission.
