The scheduled Sky Bet League One fixture with Walsall will now take place on Valentine's Night.
Peterborough United will now face Walsall on Friday 14th February (7.45pm) at London Road after the game was brought forward.
The reason behind the change is due to the scheduling of the Johnstone's Paint Trophy Southern Section area Final on Monday 17th February, which is live on Sky TV.
Any tickets already purchased for the original date of Saturday 15th February will be valid for the new date.
Tickets are on sale at www.theposhtickets.com, via the 24-hour hotline 0844 847 1934 and in person at the London Road Box Office.
