Agreeing to Shoaib's proposal, a PCB official said Shoaib's brother Shahid had conveyed to the Board that he was returning on April 26 from Mumbai, where he has gone to shoot a commercial for a motorcycle company along with Indian batting maestro Sachin Tendulkar and bollywood star Shahrukh Khan.
The Board sources said in light of the fresh information from Shoaib, the medical commission is now likely to meet on April 26 or 27 to interview him.
"The indication given has been that the Board should schedule its medical commission meeting either on the 26th or soon after as Shoaib has to report to English county Durham by May 1," a local daily quoted PCB officials as saying.
Shoaib had earlier informed the Board he would not be able to attend the commission hearing on Sunday as he had prior commitments in India.
The medical commission will also interview Moin Khan, Umar Gul, Abdul Razzaq and Shabbir Ahmed who were injured in the series.
It, however, appears unlikely that the commission would be able to interview Shabbir as he is due to leave for England today to play for Gloucestershire.
The PCB had said that if the commission found Shoaib guilty then he would face disciplinary action ranging from a heavy fine to a ban.
