6 minutes is touch and go. its unprecedented so you can understand why they didn't call straight away, but the way he fell blind freddy could tell he was in trouble.
He fell the same way some boxers do when they get a delayed ko/concussion.
Medics would've seen that & figured he had concussion (while still a bad injury, not as bad as what Phil has now obviously). It would have taken them a few minutes to realise they were treating something worse than a concussion.
Its not like theres massive differences initially between a concussed athlete & someone who suffered what Hughes has.
And its not like Phil can tell them either.
I understand its an upsetting situation, but this was an accident. No one can be blame, or is to blame. Trying to find someone to blame is only natural in the circumstances, but is quite illogical in this case
