Muslim player

[RalphtDog]

Hi folks, I am a ref wanna be, and am studying to take the test. I have a question about the following situation:

one player on a team is required to wear a head scarf because of Islamic rules. the scarf covers her head and all the way down to her shorts. teh scarf doesn't cover her face, but may interfere with her peripheral vision. It completely covers her numbers. Does this present a problem?

I am curious on how you would handle this.
