Mouth guard legal?

[Danvrapp]

Worked a GV game last night, and during garbage time with a minute or so left I notice a girl with a funky mouthpiece.

Picture a football-type mouthguard with the strap that attaches to the facemask. It almost looked as though she tried to cut off the strap...except she left what looked like a good inch attached to the guard. Definitely visible when she closed her mouth, but probably only if you had noticed it was there when she had her mouth open. Almost like a black lollipop stick poking out of her mouth.

In retrospect if I had a do-over, I probably would have had the trainer chop it off, but by the time I figured that one out the game was over.

Would anyone have done anything different? Is this a non-issue?
