Rotherham have warned they could slip back into administration if new investment is not found quickly.
The club conceded that despite "serious negotiations" there has been little progress and are now desperate for potential investors to come forward and help secure a "certain future for the club".
A statement read: "We are conscious of the need to protect the club from any possible action from its creditors.
"In order to combat this, we have therefore filed a notice of intention to appoint an administrator. This does not mean the club is in administration or even that it will necessarily go into administration.
"Instead it protects the club from possible hostile actions at a time when the club needs to be fully focussed on finding new investment.
"Clearly the threat of administration will recede if a serious investor can now be found. This is something we all want and something the club needs quickly."
