National League North side Boston United say they are unhappy that their abandoned game with Darlington on 10 November will have to be replayed.
Boston led 2-0 when Darlington's former Bolton, Derby and Birmingham City defender Nicky Hunt suffered a serious injury in the 87th minute of the game.
He was knocked unconscious and needed almost an hour of on-field treatment before being taken to hospital.
Hunt, 37, was released the following day having been given the all clear.
Boston will now make the 300-mile round-trip to Darlington on Tuesday, 16 February.
"United put forward what they believed to be a strong case to be awarded all three points, particularly in a Covid-19-condensed season, but the National League board deemed that a full rematch will be required," a club statement read.
"United are disappointed with the outcome and did consider an appeal, but given the detailed submissions already made, it was felt the decision would not be overturned."
