Low kick to the calf

Fight: 

Ricardo Lamas vs. Jason Knight,UFC 214: Jones vs. Cormier

 Ricardo Lamas landed a vicious low kick to the calf of Jason Knight putting him off balance. This low kick is underutilized in and is impossible to block. To use it correctly though, fighters need to move with penetrating force like a soccer kick while moving to the outside of their opponent’s front foot.
