The Pakistan Cricket Board (PCB) in a statement today confirmed that Irfan has been experiencing pain in his right hip region and was also rested for this reason in the match against Ireland.
"Late Monday afternoon, Irfan underwent an MRI scan. According to Team Pakistan physiotherapist Brad Robinson, the detailed report from the radiologists would be available on Tuesday," the statement said.
"A decision will then be taken on his availability for the forthcoming quarterfinal against Australia," Robinson said in the statement.
Irfan has been Pakistan's main strike bowler and an official in the board said that every effort was being made to provide him best medical care so that he can be fit for the Australia game.
"But obviously we will not take any risks with his long term fitness," the official said.
Pakistan played pacer Ehsan Adil instead of Irfan against Ireland and were able to defeat the minnows by 7 wickets to enter the knockouts.
Some television channels flashed alerts that left arm pacer Junaid Khan had been alerted in case Irfan's MRI scan report was bad.
But the PCB official said they were no plans to rush Junaid to Australia since he himself has just recovered from a knee problem and was due to undergo a fitness test at the national cricket academy in Lahore on Tuesday along with allrounder Muhammad Hafeez.
