Fighting in ice hockey [SEP] Introduction
Although often a target of criticism, it is a considerable draw for the sport, and some fans attend games primarily to see fights. Those who defend fighting in hockey say that it helps deter other types of rough play, allows teams to protect their star players, and creates a sense of solidarity among teammates. The debate over allowing fighting in ice hockey games is ongoing. Despite its potentially negative consequences, such as heavier enforcers (or "heavyweights") knocking each other out, administrators at the professional level have no plans to eliminate fighting from the game, as most players consider it essential.
