England batsman Tom Westley is facing around three months out of action after suffering a hand injury while on tour in Australia with the England Lions.
The 28-year-old right-hander was injured while fielding against a Queensland XI in Brisbane late last month and returned home for scans, before being forced to go under the knife.
A statement from Essex confirmed: "Tom has had successful surgery in Leeds on the finger injury he sustained fielding for England Lions in their three-day match against a Queensland Select in Brisbane last week.
"He will be out for around 12 weeks, ruling him out of contention for the Lions' tour of West Indies in early 2018."
Westley played in five Test matches for England last summer, averaging 24.12 in his appearances against South Africa and the West Indies.
However, he missed out on selection for the Ashes tour of Australia, with James Vince, Dawid Malan and Gary Ballance earning call-ups.
Less than two months ago he agreed a one-year contract extension with his county, tying him to the reigning County Championship Division One champions until the end of the summer of 2019.
Westley has been Essex for just over a decade and has made almost 150 first-class appearances to date.
