Pakistan off-spinner Saeed Ajmal failed his biomechanics test in Brisbane because his average elbow extension was more than double the 15 degrees allowed by the ICC.
According to the test results, Ajmal's average delivery was around an astonishing 40 degrees extension.
"There was a relatively small standard deviation of 2.5 degrees when he underwent the tests at the national cricket centre in Brisbane," a source in the Pakistan Cricket Board (PCB) said, quoting the 23-page report.
Ajmal was ordered to take the tests after match officials reported his bowling action after the first Test against Sri Lanka at Galle last month.
Match officials reported around 30 to 35 deliveries as suspect in their report to the ICC.
Ajmal, who is now suspended from bowling in international cricket and also withdraw from the national T20 championship starting in Karachi from September 17, was also previously reported in 2009 but cleared on medical grounds.
Under the new protocols for bowlers with suspect actions, medical grounds for elbow extension of more than 15 degrees is no longer acceptable.
Ajmal is slated to start working with former Pakistan spinner Saqlain Mushtaq on his bowling action from September 22 at the National Cricket Academy at Lahore.
