Plymouth's trip is also is doubt, and if they win their replay over Dagenham & Redbridge, it leaves Notts with just one home game in January which is Saturday's match with Stockport County.
Notts woul expect to make at around £30,000 from home matches, based on a crowd of around 6,000. Club Officials are concerned about the potential drop in monthly income from around a possible £100,000 to around £30,000, and with The Magpies in administration, this is the last thing needed.
"It is something we are worried about," General Manager Tony Cuthbert told the Evening Post.
"Obviously we do not want to be left with only one home match in the space of a month.
"That is a lot of income to lose and we want to avoid it if we can.
"Crewe have given us two possible dates for February, though one of those would be the replay date for the fourth round if they were to get through. And I am not sure that we would want to risk seeing the Crewe game postponed for a third time."
