The game was originally due to be played the day before at Ochilview, which East Stirling share with Stenhousemuir. However, Stenny also have a home tie - against St. Johnstone - and as it is their ground and they were drawn first, they will play on the Saturday, with the Real Saints travelling through 24 hours later.
The game still kicks off at 3pm and there will be extra time and penalties if required.
