Northamptonshire batsman Alex Wakely is set to be sidelined for the entire season, the club have announced.
The 25-year-old, who skippers the county in limited-overs cricket, suffered a ruptured Achilles tendon during the pre-season tour of the West Indies.
Wakely was injured during the first Twenty20 match of the tour in Barbados last weekend, and he will now undergo surgery early next week.
Northants confirmed that he faces "a lengthy period of rehabilitation", and he now appears unlikely to feature at all in 2014.
A statement on the Northants website read: "Northants Cricket regrets to announce that club vice-captain and limited overs captain Alex Wakely has been diagnosed with a ruptured Achilles tendon and is having an operation on Monday to repair the damage.
"There will be a lengthy period of rehabilitation for Alex and it is likely that he will miss the entire 2014 season.
"Alex wishes to place on record his sincere thanks to all those people who have made contact with him during the last week concerning the injury.
"Obviously this is very sad news for both the player and the club but we will ensure that disruption to the preparation for the season is kept to a minimum."
Wakely signed a new two-year contract with Northants in January after leading the side to their first major silverware in 21 years last summer when they were crowned domestic Twenty20 champions.
He scored a superb unbeaten 59 in the drubbing of Surrey in the final at Edgbaston, and was also the club's leading run-scorer in the Yorkshire Bank 40, making 366 runs at an average of over 36.
