Dunfermline have been handed a transfer embargo following a Scottish Football Association disciplinary hearing into the club's insolvency.
The First Division club were found to have breached Disciplinary Rule 14(g) after they went into administration last month.
As a result, the SFA have prohibited the club from registering any player over the age of 21 until 31 December.
The SFL had previously imposed the same transfer embargo until the club come out of administration as part of a punishment that also saw them docked 15 points.
The lost points consigned The Pars to the play-offs, in which they lost the first leg of their semi-final 3-1 against Forfar on Wednesday.
Bryan Jackson, the administrator in charge of the club, said: "Whilst not welcoming any sanctions which limit the club's ability to perform I believe that we got a fair hearing from the SFA and that they adequately took into account the specific circumstances that we face at Dunfermline.
"I recognise that they had to impose a penalty on the club for going into administration and believe that the transfer embargo until 31/12/2013 on players aged over 21 matches, to an extent, the existing SFL sanctions and is a reasoned response from the SFA.
"Whilst we are awaiting the written official judgement it is unlikely that we will be appealing this decision.
"The club is going through difficult times both on and off the pitch and I hope that we can now put these issues behind us and continue the battle to keep the team afloat financially and win in the playoffs."
The club will also be subject to a further 10-point penalty and be required to pay a £150,000 guarantee if they do not secure a Company Voluntary Arrangement by the start of next season.
