Shabbir was banned last December by the ICC for a 12-month period for having an illegal bowling action, after he was reported twice for his action.
The PCB filed an appeal on his behalf against the ban in January but ICC's Bowling Action Review Group (BRG) rejected it and upheld the ban.
''We know it's a difficult situation but we are making another attempt to get the ICC to have another review of his action before the ban ends. If we are successful it would be very good for Shabbir but if they don't agree there is not much we can do about it and he'll have to serve out his ban period,'' PCB Director Cricket Operations Saleem Altaf told The News.
Altaf added that Majid has left for Dubai with the latest video footage and other documents supporting another review of the paceman's action.
''But we know that the ICC or its Cricket Committee is not bound to listen to our request. The regulations allow for only one appeal but if we can persuade them there is nothing wrong in giving it another try.'' Majid is also PCB's nomination for the post of Cricket Committee chairman to replace former India skipper Sunil Gavaskar.
According to ICC regulations, Shabbir is allowed to play domestic cricket but he cannot play international cricket until his case comes up for another review on the completion of the ban.
