I am guessing this basically prevents the athlete from continuing for the day with any head injury. I would assume an outside doctor would need to make that assessment, and I think that would (and should) be beyond the scope of anything that onsite medical staff can treat.
If it's a two day competition, this would encourage the athlete to get checked out. I can't imagine a lot of doctors would clear an athlete that has a head injury, so this would at least help prevent someone suffering from a concussion from jumping right back in.
I really like these changes.
Gotcha! And I agree, I'm glad there is now a guideline for handling injuries.
