The game will now be played at Glanford Park on Friday October 8, rather than the following day as originally scheduled.
It has been moved because of a clash with England's World Cup Qualifier against Wales, which will KO at 3PM on Saturday.
Wycombe club secretary Keith Allen blasted the decision to schedule a crucial England international on the same day as a full schdule in Leagues One and Two.
He said: "The decision by the Football Association once more exhibits their complete arrogant disregard of the financial ramifications for football throughout the country, choosing to clash with almost every single day,"
