This is one area in which more importance should be placed.
In any game you do, there is to be NO jewlery worn by any participant who intends to become a player at some point during the game.
Nothing hard in the hair and nothing hard on the arm, or hand.
Now I do quite a bit of rec league early on in the year (sept-dec) And I see all sorts of jewlery being worn. When I question the coach about it, I usually get the "Well last week the refs let her play with them in" line. Now I used to think these coaches were full of sh!t. But then one day I was working a rec league game, and we were talking to the coaches, and when the coaches asked about earrings my partner said yeah, because they're new, you can tape them. Now I immediately excused myself and my partner from the coach's presence, and basically told this partner that under no circumstances whatsoever is a player allowed to participate with any jewlery on.
You let the player play, you are negligent, your insurance might not cover you if your negligent. The insurance that the site or league has might not cover you if your negligent if you were covered at all under it. Don't risk it, tell the manager, either the jewlery/beads go or I go. No exceptions, a $25 game fee isn't worth the risk of a lawsuit and legal fees.
Now to step down off of this damn soap-box
Can't you tell this is a pet peave of mine
