Alternately known as fisticuffs, bare-knuckle boxing is the original form of boxing and involves two combatants fighting without gloves or padding on their hands. Though closely related to ancient combat sports, it differs from street fighting in that there are specific rules that participants must observe, such as not striking an opponent who is already down.
