A four-man FA panel began hearing evidence on Tuesday and were expected to deliver their verdict on Friday over seven charges relating to QPRâ€™s registration of Argentine midfielder Alejandro Faurlin.
However Rangers, who have already won promotion to the Premiership, will not know their fate until the earliest possible opportunity 'thereafter'.
A statement from the FA read: "It was originally indicated that the decision of the Independent Regulatory Commission hearing on the charges against QPR and Mr Gianni Paladini concerning Alejandro Faurlin and on any sanction, if appropriate, would be announced by 4pm on Friday 6 May if possible.
"This will not now happen.
"A decision will be made and announced as soon as possible thereafter."
The latest move from the FA throws the Championship promotion and play-off picture into further doubt with the final round of fixtures taking place on Saturday lunchtime.
