The Scarborough home game on Saturday 12th October will now have to be rearranged.
They are through to the fourth qualifying round of the FA Cup after a 2-0 win away at Rylands, with the ties set to be played on 12th October.
However, on Tuesday 5th November, Oxford City are due to travel to Edgar Street in the National League North.
With both sides out of the FA Cup, with Hereford beaten 3-2 at Bishop's Stortford and Oxford losing 3-2 at home to Gosport Borough, in theory, the league game between the clubs could be brought forward to that free Saturday.
A Saturday game will get a much bigger crowd.
