The Pakistan Cricket Board is refusing to clear Shoaib Akhtar's name despite reports suggesting the injury he suffered against India was not faked.
The PCB is unhappy a medical report was leaked from a hospital in Lahore showing the paceman had sustained a genuine rib injury.
A spokesman said: "We are not happy. Shoaib will not be cleared until we receive a report from the commission."
The medical commission was formed to look into Pakistan's recent injuries.
The spokesman told BBC Sport: "The PCB has seen the leaked report, but until we know the commission's opinion on Shoaib's injury we will not comment on it.
"The report is unofficial. There will be no statement until we hear from them at the end of next week."
Shoaib presented a scan report to the four-man commission revealing a "slight injury of the 11th rib".
He hoped the evidence would prove his decision to stop bowling in the Rawalpindi Test two weeks ago was justified.
He told BBC Hindi the injury "has since healed, partially [and I have been] resting for the past fortnight".
But chairman of the commission Dr MA Wajid refused to confirm Shoaib's claims: "There were several views in the commission on Shoaib's injury."
Shoaib, Moin Khan and Abdul Razzaq underwent a series of tests in Lahore on Wednesday, with Shabbir Ahmed and Umar Gul due to be checked at a later date.
Skipper Inzamam-ul-Haq was Shoaib's most vehement critic after the fast bowler pulled out of the attack yet was fit enough to club 28 runs off 14 balls in Pakistan's second innings.
"Everyone has seen his attitude, I don't have to comment on it, but only those who are interested in playing for Pakistan should be picked," Inzamam said after India had wrapped up the series 2-1 in Rawalpindi.
