Jewelry--No earrings, piercings, watches, rings, necklaces, bracelets, wristbands, or hard casts may be worn during practice or game play. Hair bands, if used, must be elastic. Other articles that may be considered by the referee or coach to endanger either the wearer or other players must also be removed. Religious/medical bracelets and necklaces are not considered "jewelry" but must be taped to the body to the satisfaction of the referee. Failure to obey the referee will automatically disqualify the player from participation until the referee determines the hazard has been resolved. FIFA Law 4--The Player's Equipment states under safety: "A player must not use equipment or wear anything that is dangerous to himself/herself or another player (including any kind of jewelry)."
