A senior official in the PCB told PTI that the board had put on hold Butt's case.
"He met with PCB officials and had requested that we take up his case for some relaxation from the International Cricket Council before his ban ends as was done in Mohammad Aamer's case," the official said.
"But so far he has not responded to a letter we sent him on February 9 in which we had told him clearly he needed to be more honest and forthright if he harbours any hope of playing cricket again," the official added.
Butt, Aamer and Asif were banned for minimum five-year terms by the ICC's anti-corruption tribunal in February 2011 for spot-fixing and they later also served varying jail terms in the United Kingdom.

Aamer got some relaxation as he cooperated with the ICC and later confessed and apologised for his actions.
