I think the rorting of the rule by the French suggests a more formal protocol is needed.Seems that some are suggesting the blue card means the end of the match for the player concerned. Is that the case? Not sure it's the way to go if so; many players pass the concussion test after leaving following a head knock and can return to the field. Should the ref be able to in effect over-rule the team Dr?
Of course, it just might indicate a concussion test is required and the process continues as at present. But seems a bit superfluous if that's the case.
