Hughes died from a brain haemorrhage after being hit by a ball while batting two days previously.
The former Hampshire, Middlesex and Worcestershire opener was hit by a delivery from bowler Sean Abbott and never regained consciousness.
Australia team doctor Peter Brukner later confirmed that Hughes, who had been wearing a helmet, died as a result of “vertebral artery dissection”.
At the end of a five-day inquest two years later, New South Wales coroner Michael Barnes concluded that nobody was to blame for Hughes’ death.
Mr Barnes said there had been no “malicious intent” from Abbott and “no failure” to enforce the laws of the game in respect to short-pitched deliveries.
