Depression has forced Western Australia batsman Luke Pomersbach to stand down from all domestic cricket duties this season.
Pomersbach, who made his Twenty20 international debut for Australia in 2007, turns 27 on Wednesday and should be entering the prime of his career.
He has averaged 40.59 over 30 first-class matches, with his most productive season being 2007-08 when he scored 743 shield runs at an average of 61.91.
Pomersbach landed himself in trouble on Monday after failing to attend a Warriors intra-squad practice match.
The Western Australia Cricket Association immediately launched an investigation into the no-show, before releasing a statement on Tuesday revealing Pomersbach's struggles with depression.
Former WA wicketkeeper Ryan Campbell, who is a good friend of Pomersbach, said the powerful left-hander needed to step away from the sport in order to concentrate fully on his health, The Sydney Morning Herald reports.
"'He's been suffering from depression for a while and he's decided he can't be a professional athlete at this point in time due to what he's going through," Campbell said.
"So he's taking some time out to concentrate and worry about himself. The Warriors were fantastic ... they're going to support him with medical help and they said the door is always open. But right now it's all about him getting healthy," he added.
Pomersbach's most serious offence came in 2009, when he tried to resist arrest after being involved in two hit-and-run incidents while driving over the blood-alcohol limit.
