The liver punch is a punch used in boxing. It deceives the average spectator, as the punch is short and quick. The drive is usually made with the left hand, or the left hook in infighting, or the regular short body hook.
The liver punch shocks the liver, the largest glandorgan, and a center of blood circulation, and causes the victim to lose focus and drive, if not to lose consciousness outright, and can cause a breathless feeling in the victim.
It is usually delivered when feinting an opponent to lead with his right, which leaves the body exposed; the attacker then steps in and delivers a short, stiff uppercut, over the liver, which will usually put the average man out of commission at once.
Normally, a liver punch is more or less unintentional. It begins as a left hook to the body, but as the defending boxer puts his elbow down and begins to roll with the punch, the back is exposed. Thus, the attacking boxer is frequently offered either the arm or the back of the ribs, the latter of which he will usually take instead of the arm.
