The Australia captain hopeful of being fit for the one-day game with India after being forced to sit out of Friday's game.
Hamstring injury rules Michael Clarke out of Sri Lanka game
Clarke strained his right hamstring while fielding during Australia's four-wicket ODI loss to India in Adelaide on Sunday.
The Australia skipper said scans revealed that the injury was not too serious.
"I have a grade one hamstring strain so will be out of Friday's game," Clarke posted on Twitter.
Regular vice-captain Shane Watson only returned to club cricket last weekend after a six-week absence with a calf injury.
While Clarke said he hoped to return for Sunday's game against India in Brisbane, team physiotherapist Alex Kountouris was non-committal.
"(He) sustained a low grade right hamstring strain," Kountouris said in a statement from Cricket Australia.
"I will assess him later this week and decide on his availability for the game in Brisbane on Sunday."
Selectors face several decisions in choosing their next one-day squad, with Clarke's injury and wicketkeeper Brad Haddin's future key discussion points.
Haddin missed Australia's initial three matches of the tri-series, with selectors saying he was rested as Matthew Wade took his spot.
Australia's batting line-up also faces scrutiny with newcomer Peter Forrest making 66 on debut in Sunday's defeat by India to bolster his chances of remaining in the squad.
"I know the selectors are meeting today so I'll be sitting by my phone tomorrow (Tuesday) hoping to get a call," Forrest said.
"Yesterday was a great day and one I'm not going to forget.
"It was nice to contribute but it would have been a lot nicer had I got 80 plus or a hundred and got the side to a win."
