Capsey made 17 opening the batting in Sunday’s first ODI in Antigua, but suffered an injury during the home side’s reply.
The tourists secured a crushing 142-run win after bowling the West Indies out for 165 but Capsey was on her way to hospital for scans.
Any hopes of a minor shoulder problem were soon dispelled, with confirmation the 18-year-old has a fracture.
A statement from the England and Wales Cricket Board read: ‘Alice Capsey sustained an injury during the first ODI on Sunday. Upon further examination, she has broken her left collar-bone and will be unavailable for the remainder of the tour.’
England continue the 50-over series at the same ground today, with one more ODI and five T20s still to come.
