Jonathan Trott says continuing to play cricket would not be fair on his team-mates, while he recovers from a stress-related illness.
The Warwickshire and England batsman had returned to action for his county after coming home early from England's tour of Australia this winter, due to anxiety problems.
England batsman Jonathan Trott will take an indefinite break from all cricket after suffering a repeat of the stress-related illness which forced his early departure from the 2013-14 Ashes series, the England and Wales Cricket Board and his county Warwickshire have jointly announced.
England and Warwickshire cricketer, Jonathan Trott, is to take a break from competitive cricket for a second time in five months, due to a stress-related illness, according to reports on Thursday evening.
The Daily Mail reports the 32-year-old will take a break to deal with his situation.
He left the Ashes tour in November after the first Test, and Australia went on to whitewash England 5-0 in the series.
Trott has started the season with Warwickshire, and played in the County Championship match against Sussex this week.
Warwickshire's Jonathan Trott is out of the rest of the Ashes series in Australia. He flew home at the end of the first test in Brisbane, with what is being described as a long-term, stress-related illness.
Trott has been one of England's most important batsman in recent years, but he has come in for heavy criticism in Australia, getting just 19 runs in two innings as England collapsed to a 381 run defeat over the weekend.
He will be taking a break from the game, and the management at Warwickshire have said Trott has their full support. He also received the support today of former England players including the ex-Leicestershire captain Matthew Hoggard.
Jonathan Trott has taken a brave step in leaving England's Ashes tour to battle a stress-related illness, the Professional Cricketers' Association (PCA) have said.
The PCA chief executive Angus Porter said: "This does require bravery, admitting to a problem very publicly and leaving a tour and team-mates, that's the brave thing to do.
"It would have been much easier in many ways to plough on, and not address the problem, and maybe that's what people would have done 10 or 20 years ago and we'd never have known why they performed badly.
"At least we've grown up to the point that people acknowledge just as you shouldn't play on with a knee injury you shouldn't play on with a brain injury - you should seek treatment and get yourself right for the future."
Echoing the thoughts of Andy Flower, Porter said comments made by Australia's David Warner had no bearing on the illness Trott was already battling.
Warwickshire all-rounder, Jonathan Trott, has left England's tour of Australia with a stress-related condition.
Dougie Brown, Director of Cricket at Warwickshire CCC, said: “Jonathan’s health and well-being is obviously our utmost priority during this period. He is an outstanding cricketer and the Warwickshire squad will give its full support to him and his family over the next few weeks.”
Former England captain Nasser Hussain says he expects the sledging to continue in the Ashes series despite Jonathan Trott's departure with a stress-related illness.
Trott was described as "poor and weak" by Australia's David Warner after the batsman struggled in the opening test.
"I don't expect the other sledging to die down too much at all - this is an Ashes battle and it will continue to be an Ashes battle. I don't expect it to be played any differently," Hussain told Sky Sports.
The opening week of the Ashes series has been especially heated, with with Australia captain Michael Clarke warning England tailender James Anderson to "get ready for a broken f****** **arm" as he prepared to bat, a comment which has landed Clarke a hefty fine.
Performing elite sport in the heat of the media will inevitably increase the stress levels of an individual, a leading sports psychiatrist has said.
England batsman Jonathan Trott was forced to leave the Ashes tour in Australia with a stress-related illness.
Speaking to ITV News, Dr Philip Hopley, from LPP Consulting, said: "Performing elite sport in the heat of the media is inevitably is going to increase the stress levels of an individual.
"Quite often people manifesting signs of stress, their self-belief and self-confidence can be undermined impacting on performance."
While unaware of the exact details of the case, Dr Hopley said it was highly likely that the decision to leave the tour was taken in conjunction with medical professionals.
Former England cricket captain Michael Vaughan has admitted he feels guilty for criticising Jonathan Trott's performance in the opening Ashes test after it was revealed the England batsman was struggling with a stress-related illness.
Vaughan described Jonathan Trott's performance in the second innings of the first test at the Gabba as among the "worst I have seen from an England No.3".
England Managing Director Andy Flower earlier said Trott's exit was not influenced by criticism of his display.
