LAHORE, Dec 28: Shoaib Malik has to work on his bowling action and put in a lot of effort in order to get permission to continue his bowling, according to the report on his suspect bowling action prepared by Western Australian University.

The report stated that Shoaib, who had been called for the second time, during the One-day series against Sri Lanka at home by umpires Aleem Dar and Simon Taufel, had an average of his bent arm at 20.8 degree when it bowled his regular delivery off-spin but it raises to 33.4 degree when it bowls "doosra".

He bowls the first delivery at 20.5 degree, the second at 21.2, third 23.2, fourth 17.2 and the fifth 28.8. The ICC is planning to allow bent to 15 degrees from February, 2005, but it will do no good to Shoaib.

Shoaib got his arm injured while snapping a catch of English batsman Marcus Trescothick in a match at Lord's in 2001. After that incident Shoaib developed a fault in his arm, which disturbing his bowling action.

The PCB can fight Shoaib's case on medical grounds as the ICC had allowed Sri Lankan spinner Muralitharan and Pakistan's Shoaib Akhtar on similar grounds.
