High School Mandatory Sub for Injured Keeper?

[galenm]

I think it is a good idea, since the keeper has a unique circumstance under other rulings as well, due to his or her unique role on the pitch; a caution, allowing keepers who should truly leave the field [playing when "slightly" injured] may have long-term detrimental consequences that would go against the spirit of involvement and benefit if a more serious injury occurs after the keeper should have retired [even briefly] from play to be attended properly by the trainer; perhaps having the decision not rest individually with the player, or with the coach, but with an agreement between the trainer AND the coach
