Sources in the board said that chief selector Iqbal Qasim and members of his selection committee had met with Whatmore yesterday to discuss possible changes in the team after poor performance in the Champions Trophy.
"There is little time left for the team to leave for the West Indies on July 7 so the process to select the team has started," one source said.
"In all likelihood Shoaib Malik, Kamran Akmal, Imran Farhat might be out while there is also a lot of discussion also going on about the future role of Muhammad Hafeez in the team even though he is the captain of the national T20 team and Pakistan has to play T20 matches against West Indies and Zimbabwe on coming tour," he said.
The PCB is presently functioning without a chairman as the Islamabad high court has stopped Zaka Ashraf from working in this post following a constitutional writ petition against his elections in May.
"But it appears unlikely the interim Chairman would be able to represent Pakistan at the ICC meeting because of visa issues and in all likelihood it would be chief operating officer, Subhan Ahmed who have to do this job," he said.
