Ajmal, who registered his 10th five-wicket haul in the second innings of the Test match, was reported by the match officials' and they cited concerns over a number of deliveries that were considered to be suspect.
The official's subsequently sent the report to team manager Moin Khan informing him that the off-spinner's action will now be scrutinised under the ICC process relating to suspected illegal bowling actions reported in Tests, ODIs and T20Is.
As per ICC regulations, Ajmal, who has 174 Test scalps in 34 matches, will have to undergo testing of his action within 21 days, but can continue bowling until the outcome of the results, which will allow him to participate in the second and final Test starting Thursday.
This is the second instance of Ajmal being reported for suspect action. In April 2009 -- his debut year, the bowler was reported for his action while bowling the 'doosra' but was cleared the following month.
