High Quality Content by WIKIPEDIA articles! In professional wrestling a neckbreaker is any throw or slam that focuses its attack on the opponent’s neck. One type of neckbreaker involves the wrestler slamming an opponent`s neck against a part of the wrestler`s body, usually the knee, head or shoulder. The other type of neckbreaker is a slam technique in which the wrestler throws an opponent to the ground by twisting the opponent`s neck. This also refers to a back head slam where a wrestler drops to the mat while holding an opponent by their neck, without having to twist it.
