Ambati Rayudu has been reported for a suspect bowling action in the first one-day international against Australia, the International Cricket Council said in a statement.
The part-time spinner's action raised concerns among the match officials about its legality, after the match in Sydney.
"Rayudu's bowling action will now be scrutinised further under the ICC process relating to suspected illegal bowling actions," cricket's world governing body said in a statement.
The 33-year-old's action must be tested within 14 days, but he is allowed to bowl until the results are found out.
Rayudu bowled just two overs, giving away 13 runs, in the first ODI in Sydney, which India lost by 34 runs.
Adelaide will host the second ODI on Tuesday, and the final game of the series will be played in Melbourne on Friday.
