The Light Blues were set to host the Pars at Ibrox on October 12 with a 5.30pm kick-off.
But the league leaders requested the postponement on Wednesday night, with at least three players on international duty.
Lee Wallace has been named in Gordon Strachan's Scotland squad for the World Cup qualifier against Croatia, while Lewis Macleod is included in the under-21s group for their double-header against Slovakia and Georgia.
Arnold Peralta has been called-up by Honduras for qualifiers against Costa Rica and Jamaica, and Andy Little and Dean Shiels are both on stand-by for Northern Ireland.
A new date for the fixture has yet to be announced.
