# Four-wall · Rule 2.3 Gloves · C. Foreign substances

No foreign substance, tape, or rubber bands shall be used on the fingers or on the palms on the outside of the gloves. Metal or hard substances may not be worn under the glove if, in the opinion of the referee, such creates an unfair advantage.

> Part 2, Rule 2.3.C: Interpretation No. 2: A player should be allowed to protect a bone bruise on the hand. If some kind of thin bandaging material is not sufficient, the player should be allowed to use a coin or some other type of hard material, so long as the referee does not believe it creates 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.
