Football kit rules also list what players must not wear. Jewellery like necklaces, rings, and earrings are banned because they can snag on shirts or cut other players during a tackle. Watches, fitness trackers, and hard headbands are not allowed either. Even medical equipment must be safe: a plaster is fine, but a sharp pin or bulky cast is not. Studs cannot be dangerously sharp, and players cannot tape ordinary objects to their bodies as homemade protection. Referees inspect kit in the tunnel before the teams walk out. If something is unsafe, the player must remove it or change gear before the match can start. Safety rules apply to every World Cup star exactly the same as a youth player.
⚡ CAPTAIN'S ARMBAND
The team captain wears a special armband so the referee can identify who speaks for the team. It must be a proper fabric armband, not a random piece of tape, and only one player wears it at a time.
