An illegal block in the back is a penalty called in football when a player on the offensive or kicking team makes contact above the waist with an opposing player who doesn't have the ball. This penalty results in a 10-yard penalty from the spot of the foul.
An illegal block in the back penalty, also known as an illegal block above the waist, is called when a player that is attempting to make a tackle gets blocked above the waist from behind. When this happens, the referees determine where the penalty happened and move the ball ten yards back from that spot instead of from the line of scrimmage.
An illegal block in the back penalty is not called if there is a loose ball and the contact was made during an attempt to recover the ball. The penalty is also not called if a player turns their back at the last second leaving the offensive or kicking team player no choice but to block them in the back. Lastly, if a blocking player gets either of their hands on the side of the player they are blocking, no penalty is called.
An illegal block in the back penalty can be called on an offensive team but is usually reserved for special teams plays. This is because the gunners are streaking downfield and the player guarding them usually gets caught behind them. This leads them to try and make up for getting beat when the return happens and leads them to block a player in the back.

When calling an illegal block in the back, a referee holds one hand forward with their palm out and grabs their wrist with the other hand. They then push their hands forward to signal that the block in the back occurred.
