Will the HPA start looking into polo player welfare? Can they learn a few tricks from other sports like rugby?
Will they look to revise this? How do you know when a player is ready to resume play? Trusting the judgement of a non-medically qualified umpire (or senior player)! Then Fax this injury through to the HPA to notify them. No one uses FAX machines any more, this is how out of date the rule is!
