Mark Munoz took this kick from Eric Simpson, and he still won the match. MMA photographer Esther Linn did a great job of capturing the impact that a well placed kick can have, but the camera does not always tell the truth.
This has all the markings of a liver shot or liver kick, which is a kick or punch that hits the right side of the body directly over the liver. When perfectly executed, a liver shot will trigger an immediate vagus nerve reaction, resulting in excruciating pain and a fighter who drops to his knees on the spot. A TKO is a foregone conclusion. That’s because the body shuts down all non-essential systems to deal with possible liver damage.
So the fact that Munoz was not immediately dropped and went on to win the fight is proof that this was not an actual liver shot.
