The 18-month ban has been suspended by the Lahore High Court but the fine remains which Shoaib has not paid as yet.
"We have sent the notice directly to him and if he does not agree to pay the fine then we might not consider him for the Champions Trophy preliminary list (to be announced tomorrow)," a senior board official told PTI today.
Shoaib himself has been untraceable and his legal counsel Abid Hasan Minto said the fast bowler has not contacted him for consultations on whether to pay the fine or not.
"Nor have we received any copy of the notice by the board," he said.
The names of Shoaib and Mohammad Asif were included in the preliminary list by the national selectors last week but the board put its foot down and asked the selectors to come down to Lahore for further discussions.
