Sir, – A head injury assessment (HIA) is a series of checks used in elite rugby to determine whether or not an athlete is suffering from concussion and may or may not return to the field of play. Concussion is a form of brain injury. It is time to call this assessment what it is, a brain injury assessment. – Yours, etc,
