Three of the clubs just below Hereford in the National North league table have matches tomorrow evening.
If all three win then the Bulls, who have 41 points from 29 games, will drop down the table.
The fixtures are:
AFC Fylde v York City
AFC Telford v Curzon Ashton
Alfreton v Boston
Currently Boston are in 9th place with 40 points from 27 games.
Curzon Ashton are 10th with 39 points from 25 games.
York are 11th also with 39 points from 25 games.
It will be especially interesting to see how York fare as they visit Edgar Street next Saturday.
