The answer is yes, if... (not sure why Et would answer incorrectly, but we all miss things)
Here is the UIL exception:
20. 1-4-6-c Eye shields. Eye shields must be clear, not tinted, and made from molded or rigid material. Eyeglasses and goggles also must be clear and not tinted. No medical exceptions are allowed. EXCEPTION: 1-4-6-c. DELETE the last sentence that states: “No medical exceptions are allowed.” ADD: “Exception: A player(s) is permitted to participate in a UIL game wearing tinted eye shields, eyeglasses, or goggles, if the player has been issued a current season UIL Medical Exemption Form that allows for his/her participation wearing the tinted equipment. Prior to the start of each game in which the player will potentially participate wearing the tinted equipment, the Head Coach must present to the Referee of the game a copy of the properly completed UIL Medical Exemption Form that allows for the player’s participation with the equipment. Once the game begins, no player may participate wearing tinted eye shields, eyeglasses, or goggles unless the coach has presented the UIL Medical Exemption Form to the Referee prior to the start of the game.”
I do not think anyone should make a big deal out of the word, game (i.e. instead of scrimmage or practice), mentioned in the rule. If he has the sheet, he plays. I don't like the rule and think it could be dangerous, but it isn't my call.
Please enforce this and all rules correctly.
