This From Hartley Wintney:
'Ref has been out. Very sorry to inform but the game has been called OFF. Sorry to all those who have already began their travels. Shame.'
It's not yet known when Hartley will try again to stage the tie.
FA Rules say that it has to be played on or by next Saturday.
Hereford FC will need to know as soon as possible as they are set to play Alvechurch in the Midland League Cup on Tuesday evening.
Meanwhile this afternoon's game between Westfields and Stourport Swifts is ON.
