Australia all-rounder John Hastings is out of the tour of the West Indies after undergoing ankle surgery.
Hastings returned early from the Indian Premier League after experiencing pain in his left ankle.
The 30-year-old was still a chance of heading to the Caribbean for the tri-series, which also includes South Africa, but needed surgery.
Scans confirmed "early stage bone stress" of Hastings' fibula bone near his ankle, leading to surgery.
"While laid off with this injury we have taken this opportunity to undertake arthrosporic surgery to remove bone spurs in his left ankle which have been causing him concern for some time and were possibility contributing to the cause of the bone stress," Cricket Australia sports science and sports medicine manager Alex Kountouris said.
"John had this surgery over the weekend and now requires a period of rest to resolve the bone stress and recover from surgery before he will resume bowling."
Victorian Scott Boland has been named as Hastings' replacement for the tri-series, which starts on June 5.
