Per the Canada Soccer Guide to Safety (PDF):
“Players are not permitted to wear anything that is dangerous to themselves or other players. NO jewelry: that includes rings, bracelets (except medical alert bracelets — which must be either made of Velcro or similar soft material, or covered with a sweatband), earrings, necklaces, other visible body piercing, etc. The practice of taping jewelry is not acceptable.”
Please note that Canada Soccer’s guidance applies to religious or ceremonial items such as Kara bracelets or Kirpans.
