Rotherham's Football League status is under serious threat unless the beleaguered League Two club comply fully with the organisation's stringent regulations.
The League have written to the Millers to inform them of various issues - including those which could prevent their proposed move to Sheffield's Don Valley Stadium - which all need to be resolved before the club's application for League membership is accepted.
The Millers have been forced to look for an alternative stadium after they were forced to quit Millmoor, their home for 101 years, in May after new owner Tony Stewart was unable to reach an agreement with current landlord Ken Booth.
But the move to Don Valley is yet to be rubber-stamped by the Football League, who are seeking assurances that a debt to the Football Foundation/Football Stadia Improvement Fund will be settled and that the club will be able to move back to the town within a four-year timeframe.
The League are also concerned that no provision has been made regarding a £750,000 security bond which is necessary for them to ratify the move to Don Valley.
Rotherham were deducted 10 points last season for going into administration and face a potential 15-point penalty deduction after their creditors rejected a move for a Company Voluntary Arrangement (CVA) last week - although that reduction may also be increased as Luton's was as it is not the first time the club have been in administration.
The letter, published on the Football League's official website, www.football-league.co.uk, read: 'Time is short.
'It is imperative that new company's application is presented to the board prior to the start of the season and it is in the best possible shape.
'We want to reduce the risk that the board may raise further points which might prevent the issuing of a final decision before the start of the new season.'
