Phillip Hughes' father Greg was heard to say "lying" during evidence from a Cricket Australia official at an inquest in Sydney on Thursday.

The Hughes family have raised concerns through their lawyer that the cricketer was intimidated by sledging and targeted with short balls before he was fatally struck in a Sheffield Shield game.

Cricket Australia's sports medicine manager, Alex Kountouris, said he had been unaware of the Hughes family's concerns before he completed a report into the death.
