PFA Scotland revealed their first-team members at Rangers had given them a mandate to negotiate "immediate and substantial" salary deferrals to last until the end of the season.

But administrators Duff and Phelps said no consensus had been reached and a final decision had been delayed until "early next week".

PFA Scotland chief executive Fraser Wishart and Rangers manager Ally McCoist held another day of talks with administrators Paul Clark and David Whitehouse in a bid to avoid job losses.

Redundancies had been expected earlier in the week but McCoist has his squad fully intact for tomorrow's Clydesdale Bank Premier League clash with Hearts at Ibrox.

However, Wishart revealed the administrators were "highly unlikely" to accept the players' offer.

Wishart said in a statement tonight: "At yesterday's meeting the union and their solicitors were concerned that they were only being furnished with skeletal financial information.

"Nevertheless, and despite the lack of visibility on the club's full finances, the players voted to accept significant salary deferrals in the full knowledge that there remains a risk that these sums may never be repaid should not come out of administration."

On today's meeting, the former Rangers full-back added: "Unfortunately, the administrators indicated that it was highly unlikely that they would be able to agree to our members' proposal and the meeting concluded without agreement."

The administrators claimed they were still hopeful of reaching an amicable solution after a week of negotiating over job losses and pay cuts.

Clark said in a statement: "As administrators, we had anticipated completing our review of staffing levels and cost structure of the Rangers business this week but the participation of a number of players in international fixtures did interrupt the process.

"In short, the Rangers business is trading at a substantial loss and we have no alternative but to fill an approximate £4.5million shortfall by the end of the season.

"It is therefore imperative that we find savings of approximately £1million per month to ensure the ongoing viability of the business.

"As has been widely publicised, there have been a number of discussions this week in an effort to achieve the necessary cost reductions.

"We are determined that all realistic options should be explored and today discussions have been ongoing with Ally McCoist who, in turn, has been speaking to his players and the PFA Scotland.

"We would prefer to reach a consensual position but as the day has gone on and tomorrow's very important match against Hearts looms larger, it has been agreed that any final decisions have been postponed until early next week."

Wishart also retains some hope of avoiding redundancies. So far only director of football Gordon Smith and chief operating officer Ali Russell have left since the club went into administration on February 14.

Wishart said: "It remains our members' belief that their offer of wholescale wage deferrals addresses the administrators' goal of achieving short-term cost reductions and would also serve to assist ongoing discussions with potential investors.

"It is still our members' wish to reach a consensual position with the Duff and Phelps which will achieve the administrators' objectives, avoid redundancies and ensure that no player's employment is brought to an end in breach of contract."

There was some good news for Rangers supporters today, potentially, after it emerged Duff and Phelps had secured an initial court order to seize £3.6million held in an account of Rangers owner Craig Whyte's lawyers, Collyer Bristow.

It was previously revealed that £24.4million from investment company Ticketus, who bought rights to future season ticket sales, had been paid into an account held by the London-based law firm.

The club's £18million debt to Lloyds Banking Group was then paid off from the same account after Whyte took over and administrators have been seeking clarity on the remainder of the sum.

The statement read: "We can report that we made this week an emergency application to the High Court in London to secure money held in the client account of solicitors, Collyer Bristow, who had acted for the purchaser of the club in May 2011.

"We can confirm that following the court hearing Collyer Bristow paid approximately £3.6m to our lawyers, Taylor Wessing, to be held securely by Taylor Wessing until the High Court decides whether or not it is the club's money.

"Collyer Bristow will also disclose to Taylor Wessing details of the payments of funds out of their account on behalf of the club since May 2011.

"The High Court in London will hear further representations on the administrators' claim to the money and our request for further information from Collyer Bristow on March 8.

"Since legal proceedings are ongoing we cannot provide further information but this is a positive step in the administrators' investigations into the club's financial affairs."

Other developments today included confirmation from the Scottish Football Association that they will investigate claims made by former Rangers director Hugh Adam that payments made to players were not disclosed to the football governing body.

The SPL announced all 12 clubs would meet on Monday to discuss rules surrounding financial fair play.

But the focus will turn to football tomorrow as Rangers host Hearts with less than 3,000 tickets available late this afternoon.

The statement from Clark continued: "Right now, the situation is quite simple - income generated now will help secure the future of Rangers and we encourage supporters, who have shown tremendous backing for the club throughout this process, to buy tickets for the Hearts game at Ibrox tomorrow and future home matches."
