When a player legitimately goes down injured writhing in agony 9 out 10 times there will be physical evidence almost immediately, a broken jaw, fractured cheek bone, busted orbital bone all are followed by bruising and lumps and bumps.
The ref should have waited for the treatment on the pitch...
With all the incidents that happened in that spectacular game, we would have been there till 9pm trying to make sense of all the mayhem going on most of it attributed to that god awful ref.
