Karachi, Apr 5: Demanding an explanation for his statements on the ban imposed on fast bowler Shoaib Akhtar, the Pakistan Cricket Board has warned Chief coach Geoff Lawson against making further comments on issues which were "not in his domain".

"We have told Lawson we would like him to concentrate on his job and leave administrative matters to the Board in future. He has great responsibility on his shoulders and shouldn`t be commenting on such issues," a senior official said.

"We have asked Lawson for an explanation as he is not supposed to give media statements on matters which are not in his domain. Certainly the ban on Shoaib is purely an administrative matter of the Board," he added.

Lawson had said that Shoaib`s ban was sad and that the fast bowler had lot of potential but lacked responsibility. He had also said Shoaib`s ban was a loss to Pakistan cricket.

The official said the Board had also taken note of statements made by batsman Younis Khan and a member of the Board`s governing body on the ban.

Sources said Lawson had been told by senior officials to avoid speaking to the media on contentious issues as it created more controversies and damaged the image of Pakistan cricket.

"Lawson has also been advised to avoid giving comments to foreign publications on contentious issues like the Shoaib Akhtar ban," one source said.

The PCB recently introduced some stringent clauses in the central contracts for players making it clear they couldn`t speak to the media without the permission of their manager or Board.
