Amit, who helped his side beat Bangalore by a convincing seven wickets at SuperSport Park here, joined his team-mate Kamran Khan in the suspect bowling action list after on-field umpires Daryl Harper and K Hariharan reported him.
Amit's case has been referred by the IPL to the Rajasthan Royals team management and the IPL Technical Committee for further scrutiny under Law 24.3 of the Laws of Cricket.
"After the game against Royal Challengers Bangalore at SuperSport Park, TV footage was obtained and examined by all the three umpires, including TV umpire Tyron Wijewardene. They decided further action was necessary under Law 24.3 of the Laws of Cricket," the IPL said in a statement.

"The matter has been referred by the IPL to the Rajasthan Royals team management and the IPL Technical Committee," the statement added.

The 27-year-old little known medium pacer, who plays for Gujarat in Ranji Trophy, however, can continue playing until he is proven guilty of an illegal action.

Amit, who has taken seven wickets from two IPL matches, was adjudged Man of the Match for his sterling display yesterday as Rajasthan beat Royal Challengers by seven wickets.

Amit's Rajasthan team-mate and left-arm pacer Kamran has been ordered two weeks rehabilitation by the IPL Technical Committee after being reported for suspect bowling action in their match against Chennai Super Kings here on April 30.
