Portsmouth's future could become clearer on Friday after former owner Balraim Chainrai re-entered the running to buy back the club.
Just eight days ago Chainrai's company Portpin announced their interest in Pompey, who remain in administration and in danger of liquidation, was at an end.
Their decision appeared to pave the way for fans' group the Pompey Supporters' Trust, backed by a loan from the local council, to complete their rescue of the club.
Yet Hong Kong businessman Chainrai remains Portsmouth's biggest creditor and, having expressed doubts about the viability of the PST's bid, he has now submitted a fresh offer to administrator Trevor Birch.
And according to Birch, the PST will submit their latest bid tomorrow.
Birch said: "Portpin has submitted a new offer and we are now reviewing it.
"We have been working with the Trust since Portpin's original offer was withdrawn and understand that the Trust is on track to submit a business plan and revised offer tomorrow.
"We will assess its bid once it has been submitted and will then determine which offer provides the best deal for creditors, as is our duty as court appointed administrators."
