Off-spinner Harbhajan Singh is doubtful for Tuesday's third Test against Australia because of fever, adding to India's fitness worries as they try to square the four-Test series.
Harbhajan, who has taken 51 wickets in seven matches against Australia, missed practice on Monday although a team official said he was hopeful he would recover in time.
Nicknamed the "Turbanator" after taking 32 wickets to inspire India to a 2-1 victory over Australia in 2001, Harbhajan picked up 10 wickets in the first Test in Bangalore, won by Australia by 217 runs.
India are already without first-choice paceman Irfan Pathan, who sustained a side strain in the drawn second Test in Chennai. His place will be taken by medium pacer Ajit Agarkar.
Captain Sourav Ganguly is suffering from a groin strain but said he would be fit to play.
The 32-year-old suffered the injury while fielding during the Bangalore Test.
"I have a bit of a problem, but it's not major. I'm all right," Ganguly said.
