Rangers has entered administration - meaning the football club will be docked 10 points, effectively ending its Scottish Premier League challenge.
It follows an unsuccessful legal bid by HM Revenue and Customs at the Court of Session in Edinburgh to appoint its own administrator.
It has now emerged that Rangers' game against Kilmarnock on Saturday may not go ahead unless police can be paid.
Rangers owner Craig Whyte confirmed Tuesday that the club had filed legal papers to appoint administrators.
It was initially thought that the club had 10 days to make a decision on whether to proceed, but the HMRC action changed the dynamic of the situation.
The two parties are at loggerheads over a disputed tax bill and penalties of up to $90 million.
