Lack of medical attention for Phillip Hughes has been ruled out as a factor in the cricketer's death by an independent report which calls for mandatory use of helmets by batsmen and close-in fielders.
Cricket Australia's review into the death of the former Test batsman recommends helmets be compulsory for batsmen facing pace bowling in nets and games.
But it stops short of making it mandatory for helmets to have clip-on guards at the rear of the helmet.
Such guards were introduced after Hughes died on November 27, 2014, two days after being hit in the neck while batting for South Australia against NSW in a Sheffield Shield game.
The report, by President of the Australian Bar Association David Curtain QC and released on Wednesday, reviewed the medical treatment given to Hughes.
