After further aggravating his left hamstring injury in the One-Day International tri-series defeat to Zimbabwe in Harare, Australia captain Michael Clarke is to return home and miss the remainder of the series.
However, during the course of his innings of 68 not out, he was forced to retire due to the hamstring problem, and although he returned for the end of Australia's innings, and later bowled an over of left-arm spin, his tour is over.
The news compounds a poor day for Australia, who lost the match by three wickets with two overs remaining.
"Michael aggravated his left hamstring while batting during the ODI against Zimbabwe today and will not be able to take any further part in the tri-series," Cricket Australia physiotherapist David Beakley said.
"Michael will return to Sydney on Tuesday to undergo scans and further assessment to determine the full extent of the injury."
George Bailey, who led the side in the first two matches, will be expected to captain when Australia meet South Africa on Tuesday (2nd September).
For Clarke, he now faces a nervous wait to see whether he will be fit to travel to the United Arab Emirates where Australia play Pakistan in October.
