India batsman and part-time off-spinner Ambati Rayudu has been reported for a suspect bowling action during his side's Gillette ODI against Australia in Sydney.
Rayudu's action was cited by match officials after he bowled two overs for figures of 0-13 during the series-opener, which Australia won by 34 runs.
India's No.4 was later trapped lbw by Jhye Richardson for a second-ball duck.
The 33-year-old must undergo testing within 14 days but is permitted to continue bowling until the results of the tests are known, the International Cricket Council (ICC) said in a statement on Sunday evening.
Should he fail the independent biomechanical testing, Rayudu faces being suspended from bowling in international cricket until he can correct his action.
Rayudu, who retired from first-class cricket late last year to focus on limited-overs cricket, has played 46 ODIs and six T20 internationals for India.
