Rangers football club are expected to draw the biggest crowd in the UK when they play their first match since appointing administrators on Tuesday.
Fans have responded to the financial crisis by making the home game with Kilmarnock, at the 50,000-seater Ibrox stadium in Glasgow, a "full house".
Rangers chairman Craig Whyte will not attend the match.
But Mr Whyte said on Friday that he had "absolutely nothing to fear" from any inquiry into his purchase of the club.
The Scottish Premier League club went into administration on Tuesday, with HMRC pursuing an unpaid £9m tax bill accrued since Mr Whyte assumed control at Ibrox in May 2011.
Questions have also been raised over the whereabouts of £24m paid to the club by the firm Ticketus for future season tickets.
Rangers were given a 10-point penalty for going into administration, leaving the club 14 points behind Celtic in the SPL race.
'Dreadful time'
The Scottish Football Association has also announced it will conduct an inquiry into the activities of Rangers.
The SFA said it was concerned about potential breaches of its rules which had come to light.
The administrators welcomed the investigation and have also thanked supporters for "the tremendous way in which they have responded to the club over the last few days".
A near capacity crowd is expected at Ibrox and, with English giants Manchester United knocked out of the FA Cup and Arsenal playing away, it should be the biggest attendance of the weekend.
Fans buying last minute tickets at the ground told BBC Scotland they wanted to show their support at what was a "dreadful" time for their club.
One supporter said: "It is the uncertainty, that no-one really knows what is going on, that is bothering everybody.
"We just want a bit of clarification that we can go to games in the future, and enjoy watching Rangers, like I have done since I was a young lad."
In a statement released on Friday Craig Whyte said he understood fans' anxiety.
He said he knew the supporters would use the game to "prove why you are the best football fans in the world".
'Fighting chance'
He added: "Although I would dearly love to be at Ibrox for the game, my priority is, and will continue to be, to assist the administrators in any way I can to bring this process to as speedy a conclusion as possible.
"Painful though it is for all concerned, administration now gives Rangers a fighting chance - a welcome breathing space - to fix major structural problems that will allow the club to grow and prosper again both on and off the field.
"So I send Ally McCoist and the team my very best wishes for tomorrow."
The SFA is already investigating whether Mr Whyte is a fit and proper person to own a football club.
In a statement it said that inquiry had been restricted by the failure of the club's solicitors to share information.
It added: "We now feel there is no option but to undertake an independent inquiry to establish the clear facts and to determine the extent of any possible rules breaches."
On Thursday, Strathclyde Police confirmed it had been passed information regarding the ongoing situation at Rangers Football Club, and was examining it.
Former chairman Alastair Johnston has also asked the Crown Office to investigate Mr Whyte's acquisition of Rangers.
Mr Whyte has insisted he has not been involved in any "criminal wrong-doing."
He said he was "100% confident" administrators would prove that all money that had come in and gone out of the club during his tenure has been properly accounted for.
Administrators Duff and Phelps said they would continue to ensure the club's business was "run seamlessly" as a plan to exit administration was developed.
Some might say it's a bullshit story that nobody cares about, but I found it pretty momentous tbh, even with one of the worst times in the clubs history, we'll have the biggest crowd in the UK tomorrow. Over 51,000.
