Haw. Code R. § 16-74-436
If a boxer receives an injury causing blood to flow, the contest cannot be interrupted for the purpose of stopping the flow of blood unless, in the opinion of the referee, the injury is such as to render the injured person incapable of going on. If the second cannot stop the bleeding during the one minute rest period, and if in the opinion of the referee, the boxer may be suffering pain which puts him at a physical disadvantage, or is likely to be seriously injured, he should stop the contest without hesitation, notwithstanding the boxer may want to continue. The decision as to whether a boxer is unfit to continue remains exclusively with the referee, who should, if necessary, seek the opinion of the attending physician. The referee has the right, after consideration of the situation, to stop the contest, but at the same time it is his duty to see to it that the injured boxer, or the apparently weaker man, is not robbed prematurely of his chance of victory.
