Ireland all-rounder John Mooney has left the team's tour of the West Indies because of a stress-related illness.
News of Mooney's departure came during Monday's game against Jamaica, which the Irish lost by six wickets.
Cricket Ireland said the 31-year-old had been having treatment "for some time" but that his condition had "deteriorated" in the past 24 hours.
"The decision was taken to get him home as quickly as possible to resume his treatment," a statement added.
"He is returning to Dublin to be with his family and will take no part in the remainder of the tour."
The statement did not make clear whether Mooney will return to the squad for the World Twenty20, which starts in Bangladesh in mid-March.
Cricket Ireland chief executive Warren Deutrom described Mooney as an "incredibly passionate cricketer" who had "performed with distinction for Ireland over more than a decade".
He added: "Cricketing matters come a poor second where health issues are concerned.
"The most important thing for John is to get the support and care he needs to aid his recovery. Cricket Ireland will endeavour to do all that it can to aid this process.
"John and his family have asked for privacy while he recovers and I would urge everyone to respect their wish at this difficult time."
Mooney has become a key part of a steadily improving Ireland squad since making his debut in 2004.
The Dubliner played a crucial innings, and hit the winning runs, in a shock World Cup victory over England in 2011.
And he was named man of the match in the Irish victory over Afghanistan in the Intercontinental Cup final in December.
But last year he was "severely reprimanded" by Cricket Ireland and banned from a one-day international after sending a number of controversial tweets following the death of Baroness Thatcher.
