Reading the updates - I reckon we've stuffed this up
"It has been accepted that there was a classifiable offence to the head, and carelessness."
And even better;
"Brennan admitted to pinning Cordner at the elbow, which isn't the same as pinning down by the sides of the body but he says it's pinning nonetheless."
Really should have attacked the perspective that this warranted any sanction, rather than trying to be Cool Hand Luke and working within the system.
