The ICC confirmed on Wednesday that the sanctions against Asif and Butt will expire at midnight on 1 September and they will be eligible to return to competitive cricket, at both domestic and international levels.
A well-placed source in the PCB said that the Board was also caught by surprise by the ICC statement and were not prepared for the reactions that followed.
"With regard to the ICC's announcement on lifting of sanctions against Salman Butt and Muhammad Asif the PCB has sought further clarification from the ICC. Until the world body's response has been received and evaluated, PCB shall not be making any further comment on this issue," the PCB said in a statement on Thursday.
Both Butt and Asif are scheduled to play for Lahore teams in the National T20 event next month but the source said the PCB is yet to make up its mind on whether to allow them such a quick comeback into domestic cricket after such a major crime.

"Their ban ends at midnight on 1st September the same day the event starts and the PCB is worried if they start playing the next day whether the right message will be sent out in Pakistan's cricket circles and to other players," the source said.
The PCB however has no reservations over the future of Muhammad Aamir who has already resumed playing domestic cricket after the ICC this year allowed him to resume domestic cricket in his ban period under a special relaxation allowed to him in the revised anti-corruption code.
Both Butt and Asif who are seen as the main culprits in the spot-fixing scandal that rocked Pakistan cricket in 2010 in England on Thursday gave statements in the media reiterating they had committed a mistake and apologized to God and the nation and asked for forgiveness.
Asif also insisted that people and former players should accept the fact that they had completed their punishment for their wrong doing and should not be given a second chance to redeem themselves and show everyone they will not repeat the same mistake again.
