England batsman Jonathan Trott has been suffering with a stress-related illness for some time, England team director Andy Flower has revealed.
"Trotty has been suffering from a stress-related condition for quite a while," he told a press conference televised by Sky Sports News.
"He's always managed it very successfully and he's been a brilliant international batsman for England and hopefully will continue to be a brilliant international batsman for England in the future.
"But he needs time away from this environment for a while, he needs time with his family, he needs time to reassess and spend some time with his family.
"This isn't the type of environment for that type of rest and recuperation that he requires."
