Australia's Mitchell Marsh has been ruled out of next month's Champions Trophy with a back injury, with the allrounder needing an "extended period of rehabilitation".
Marsh struggled with the compliant during their recent home test series against India and Cricket Australia said the problem had not "responded sufficiently".
"Mitchell Marsh has been ruled out of the upcoming ICC Champions Trophy with ongoing lower back pain and dysfunction," the governing body said late on Friday.
"His lower back pain flared in recent weeks, leading the National Selection Panel to make the longer term decision for Marsh to complete a more extended period of rehabilitation."
A replacement will be named later, with the deadline for final squads on 12 February.
The eight-nation Champions Trophy will be hosted by Pakistan and the United Arab Emirates between 19 February and 9 March.
