Chesterfield FC will replay their Second Round Proper tie today after a breach of an FA rule meant their win against MK Dons was discounted.
The club played an "ineligible" player - Georg Margreitter on loan from Wolves - in their 1-0 win on 6th December. He didn't have written permission to play in the match.
The tie will played to a finish, with no further replay.
The FA said no further action will be taken against the club.
Chesterfield have achieved promotion to League One after a 2-0 win away at Midlands rivals Burton Albion.
Chesterfield have been beaten 3-1 by Peterborough at Wembley in the final of the Johnstone's Paint Trophy. 2 nil down from the first half, Eoin Doyle gave the Spirites hope of a comeback early in the second half but Brit Assombalonga's penalty 15 minutes from time sealed the win for Peterborough.
