Derbyshire all-rounder Peter Burgoyne has been granted time off to deal with "stress-related issues".
The 20-year-old has been struggling for some time and the player, club and the Professional Cricketers' Association have agreed he should have an extended period of absence.
"The pressures on young cricketers can be very challenging to handle," said chief executive Simon Storey.
"We'll do all we can to support him as he concentrates on a full recovery."
England Under-19 international Burgoyne made his Derbyshire debut in 2011 and is seen as one of the club's most promising young players.
Storey added: "We are obviously disappointed that Peter won't be actively involved with final preparations for the new season. He is an exciting young cricketer with bags of potential and a promising future.
"We have a number of welfare programmes in place at the club while the PCA and ECB (England and Wales Cricket Board) also offer extensive support to players and staff."
England batsman Jonathan Trott left England's tour of Australia over the winter because of a stress-related illness, but he is set to make his comeback for Warwickshire next month.
