The Indian opening batter did not attend India’s training sessions at the Chidambaram Stadium on Wednesday and Thursday, as the Indian team management was hopeful that he will make a recovery.

“He is under the weather,” the official update from the BCCI said. “The medical team is closely monitoring him. We are hoping he gets better soon.”

Gill is the leading run-getter in ODIs this year with 1,230 runs at an average of 72.35 and a strike rate of 105.03. He smashed two centuries and a half-century in his last four outings in ODIs, two of which came against Australia.

In case Gill is unavailable for Sunday’s game, KL Rahul or Ishan Kishan could open in his place with skipper Rohit Sharma.
