Australian fast bowler John Hastings has retired from all forms of cricket fearing a mystery ailment could lead him to bleed to death on the field.

The burly all-rounder, who has represented his country in all three formats of the game, revealed last month he was struggling with an illness that causes him to cough up blood whenever he bowls.
He first noticed the issue several years ago and despite a battery of tests and operations is no closer to knowing why it happens.
