Warwickshire captain Jim Troughton is to undergo surgery on his back.
The 34-year-old batsman will have the operation next week and will therefore miss the club's pre-season tour to Barbados.
Warwickshire director of cricket, Dougie Brown, told the club's official website: "After missing the latter part of the 2013 season with an injury to his lower back, Jim has been taking a full part in the team's pre-season programme since we returned to training in November.
"However after suffering further discomfort it is clear that he now needs to undergo an operation.
"Whilst it is frustrating to lose Jim for what is an important period of preparation we must give him the best possible chance of regaining full fitness as soon as possible.
"His absence will give some of our young batsmen more time in the middle whilst we are in Barbados and help them challenge for a place in the starting XI when the domestic season gets underway."
Troughton was hampered by the injury last season, in which he made just seven County Championship appearances, during which he scored 322 runs at an average of 32.20.
