Redbridge Jewish Care A face possible expulsion from this season's Peter Morrison Trophy following allegations that they played an ineligible player in the previous round.
Last season's double winners' 2-0 win over Hendon United A is being investigated over a possible administration error. The hearing takes place on Monday.
Sunday's scheduled quarter-final against Hyde Park Rovers has been postponed.
Hendon manager David Garbacz said: "We are aware that the league is looking into the possibility that they might have played an ineligible player. We will abide by any decision the committee make after that hearing."
Redbridge and the competition organisers declined to comment.
