Australia captain Michael Clarke is unlikely to be fit for Sunday's tri-series one-dayer against India, while allrounder Mitchell Marsh is in doubt for the remainder of the season.
Clarke, who injured his hamstring during Australia's loss to India last week, sat out Friday's match against Sri Lanka as team medical staff wanted him to continue to rest his injury.
"I've got a little hamstring strain. It's on the mend. It's probably unlikely I'll be picked for Brisbane, though," Clarke told Channel Nine television on Friday.
"I've done a lot of work over the last couple of days and (team physiotherapist) Alex Kountouris would prefer me to rest but I'm not far away at all."
Ricky Ponting returned to the captaincy as stand-in skipper for Clarke in Friday's tri-series one-dayer against Sri Lanka.
Marsh, the younger brother of test batsman Shaun Marsh, has a lower-back bone stress injury and will undergo further tests to assess when he will be fit to return to the one-day squad.
Kountouris said Marsh is not expected to be able to bowl for the remainder of this season.
The Australia selectors will assess whether they need a replacement player for Sunday's ODI against India in Brisbane.
