India captain Jasprit Bumrah left the Sydney Cricket Ground to be examined for an unspecified injury after lunch on the second day of the fifth Test against Australia, media said on Saturday.
Television footage showed the fast bowler, who has been the most influential player in the five-match series, leaving the field about an hour after the first break of the day.
Bumrah, who dismissed Marnus Labuschagne in the morning session to take his series to 32 wickets at an average of 13.06, did not take the field after the lunch break.
No one from the Indian team was immediately available for comment.
India, who left out captain Rohit Sharma for the match, need to win in Sydney to square the series 2-2 and retain the Border-Gavaskar Trophy.
