On another point. Someone, somewhere is not going to get the help they need immediately on the pitch because players are now overacting to a ridiculous degree and that includes faking head injuries because they know the ref will probably stop the play.
As a thought, what if Eriksson had collapsed just after a fairly innocuous challenge? The ref would have waved play on and Finland would have bombed up the pitch assuming he was play acting trying to get play stopped. That could have been the difference between Eriksson surviving and dying, imagine how the ref would feel in that situation?
I would have thought a proper way to pay thanks for Eriksson not being more seriously injured would be to realise that perhaps dropping to the floor screaming in an attempt to con the ref is not doing anyone any good should that circumstance rise again in less clear cut circumstances...
