Injury-hit Alfreton Town will have to play an outfield player in goal for Tuesday's FA Cup fourth qualifying round replay against Lincoln City.
Only players who are registered in time for the initial game are eligible to play in the tie.
"It is an extraordinary set of circumstances," said boss Nicky Law.

Conference Premier side Alfreton only brought in the Scunthorpe goalkeeper last week as cover for another loan signing Cameron Dawson, who also has a thigh injury.
Severn was injured during Saturday's match but still played on.
Law added: "We sought dispensation from the Football Association first thing this morning but they have turned it down.
"We have just 11 fit players, one of whom is going to have to play in goal.
"We are not complaining, and we have already checked with the FA that we will not be fined for fielding a weakened side."
