A player should be allowed to protect a bone bruise on his hand. If some kind of thin bandaging material is not sufficient, he should be allowed to use a coin or some other type of hard material, so long as the referee does not believe it gives him an unfair advantage, in which case the material would be disallowed. Any such protection must be worn under the glove and must be approved by the referee before play begins.
