The Park Hall surface is currently playable under a light covering of snow and putting the game back a day means it is almost certain to go ahead.
Kick-off time will be 3.45pm and, with Newtown's home game against Llanelli a serious doubt, S4C cameras would switch to Oswestry for the live game.
Special admission prices of £5 adults, £3 concessions, will be in effect for the fixture, which is likely to be the only game played within a wide radius of Oswestry.
The club would appreciate any voluntary help to clear snow from the surface and spectator areas on Saturday morning.
