Northampton Town will travel to Valley Parade for a replay after coming from behind to draw with Bradford City.
The Bantams took the lead when new signing Alan Connell set up Will Atkinson, who fired home from the edge of the box.
The Cobblers equalised when Louis Moult headed in Danny East's cross.
Connell and Atkinson went close for the visitors late on, while Town's Adebayo Akinfenwa had two shots saved, but both sides had to settle for a replay.

Northampton Town manager Aidy Boothroyd told BBC Radio Northampton:
"In the first half, we were poor by our standards. We didn't do anything to get our crowd going, even though we had a few shots at goal, and Matt Duke was in inspired form.
"We were much more incisive in the second half and we were pushing to try to score, rather than trying to look nice.
"I'm glad we've stayed in the FA Cup because it's important to us as a club, but I'd have liked to have it done and dusted.
"There may be one or two players that come back into the club and there may be one or two things that need shaking up."
