The oblique kick AKA the Savate kick targets an opponent’s knee and is one of Jon Jones' trademark moves. Here is another counter on display by Sage Northcutt
Although this is probably a low blow, Sage is able to counter Thibault Gouti’s oblique kick with a low sidekick to the supporting leg. It is due to the diversity of fighting disciples that are put to the test in MMA make moves like this possible. It is a great counter, but if you get to try this in sparring please be careful as you can hurt your partner’s knee if you land a sidekick with significant force.
