"We can't look beyond the replay but I am sure it is not the tie that any of the 3 teams involved were really dreaming of," said Cobblers boss Stuart Gray.
"At least whoever wins the replay will be at home, and I am sure all of the 3 teams involved will see it as a chance to potentially win through to round 4 and pull out one of the bigger teams then.
"From our point of view we have 2 very important league games this week to look forward to, and then of course we have the replay which will be very difficult and we are not thinking any further than that at the moment."
