Ashington FC are to lodge an appeal with the FA after being removed from the Brooks Mileson Memorial League Cup last week.
The Colliers got through to the final of the competition after a 3-1 victory over Newton Aycliffe in the semi-finals.
But it was later revealed that one of their players was not registered within the competition’s required 14-day rule.
Chairman Ian Lavery and football secretary Brian Robson represented the Woodhorn Lane club at a meeting of the management committee of the Ebac Northern League last Thursday and presented their case.
But the outcome saw the club disqualified with Newton Aycliffe reinstated.
Mr Lavery said: “The result of the meeting saw Ashington disappointingly withdrawn from the League Cup with no financial penalty.
“Consequently the club have decided to appeal the decision to the Football Association.”
Mike Amos, chairman of the Northern League, said: “I’m limited in what I can say because of the appeal.
“I would, however, like to make the point that in accepting the charge, Ian Lavery and Brian Robson acted with an honesty and dignity that reflected very well on the club.
“The circumstances are very unfortunate, especially for a good and progressive club.”
In the other semi-final played last midweek, Shildon beat Dunston UTS 1-0.
