Pakistan Cricket Board on Monday made it clear that though there was no bar on Pakistani players to participate in the IPL, the cricketers cannot sign contracts directly with the Indian Board or the participating teams.CEO of PCB, Shafqat Naghmi, said since the league was approved by cricket Boards of Pakistan, India, Australia, South Africa and England, no player could sign individual contracts to play in the league."Their contracts would be through the PCB and would be regularised because we wish to ensure our key players don't play too much cricket and are always fit for national duty," Naghmi said.Pakistan has announced it would be hosting its edition of the premier league next year in October-November with four foreign players allowed in each of the six teams to be franchised out to corporations and companies.Naghmi said the ICC had assured them that the Champions League would not be played without the participation of Pakistan in it.Sources said the Pakistan board is now trying to woo back Inzamam-ul-Haq, Mohammad Yousuf, Imran Farhat and Abdul Razzaq, who have joined the rebel Indian Cricket League."The four have been told they can now play in the official IPL and make money with the permission of the Board besides being available for national selection," a source said.
