''Following specialist medical advice received by the England selectors, opening batsman Marcus Trescothick will not be named in the 14-man squad for October's ICC Champions Trophy in India,'' an England and Wales Cricket Board (ECB) statement said.
Trescothick has asked the ECB to omit him from the squad on the advice of Performance Healthcare, the specialists treating him.
''After his return from the tour of India in March, Marcus sought specialist help for his ongoing symptoms. In addition to the deleterious effects of the acquired gastrointestinal infection on his health, it later became evident that he was also suffering from an underlying stress-related illness.
''He has been receiving specialist treatment, which has allowed him to resume his position in the England team. However, we believe that it would be premature for him to tour India in October. Rest is an important part of his treatment and he will need recovery time before the Ashes tour of Australia which begins in November,'' Press Association quoted a spokesman of the specialists firm as saying.
Trescothick, a key figure for the Ashes series and next year's World Cup, had been in poor form of late and managed just 22 runs in the three ODIs against Pakistan including the first-ball duck in the third ODI at the Rose Bowl yesterday.
The 30-year-old left-hander, who plays for Somerset, is England's all-time leading century-maker in One-day cricket with 12 hundreds in 123 matches.
England selectors will have to name the squad on September 10 at the latest, after International Cricket Council (ICC) gave them three more days even though tomorrow is the last day for other countries to name their squads.
