LAHORE - The Pakistan Cricket Board are still undecided on punishment for players who left the rebel Indian Cricket League, putting a question mark on their participation in the national team's Test tour of Sri Lanka starting June 27. A senior official of the Pakistan Cricket Board (PCB) said Chairman Ijaz Butt would decide whether the players, who intend to severe ties with ICL by the May 31 deadline, would be allowed back into the national team after a cooling off period or could do so by just paying fines. "We will put up the case to the Chairman. He will take a final decision. But the International Cricket Council (ICC) has advised its member boards to have a cooling period of six to 12 months under a clause in the regulations on unauthorized tournaments," PCB chief operating officer Saleem Altaf said in a report. Senior batsman, Mohammad Yousuf had submitted an NOC from the ICL to the board confirming termination of his ties with the unofficial league. Other players including Abdul Razzaq, Rana Naved, Imran Nazir have also stated they have been released by the ICL which recently freed around 50 local and overseas players from their contracts. Yousuf said he was hopeful of making a comeback to the Pakistan team soon.
