American consortium; Blue Knights and Brian Kennedy make bids
Chicago-based consortium Club 9 Sports is one of three confirmed bids in the running to take over the ownership of financially-crippled Rangers.
A spokesman for the consortium, which describes itself as a group of "sports specialists", said the bid had been submitted to the club's administrators ahead of the Friday deadline for first indicative bids.
The investment firm has previously failed with investment offers in Sheffield Wednesday and Tranmere.
Earlier, manager Ally McCoist was informed by the club's administrators Duff and Phelps that they were expecting a number of bids to materialise.
"If it was a dangerous situation and I could be of assistance then of course I would I think there are enough people hopefully there who are going to be in good shape to take it where it was," he said.
Former Rangers director Paul Murray and his Blue Knights consortium have also confirmed their bids.
Ticketus, the firm which provided £24.4million for Craig Whyte to take over the club last year, is part of the Blue Knights.
Murray confirmed his group had submitted their bid, telling Sky Sports News
: "We're ready to go, we have the finances in place and we want to get the club stabilised as quickly as possible."
And Sir David Murray says he approves of the Blue Knights' proposal, commenting: "I have nothing but respect for Paul - he only has the best interests of the club at heart. He is a genuine Rangers man and wants the best for the club."
Brian Kennedy, owner of English rugby union club Sale Sharks, is the third confirmed bidder for the club.
A brief statement read: "Brian Kennedy confirms he has lodged his bid with the administrators."
Administrators Duff and Phelps later revealed that more bids could be on the way amid "worldwide interest".
Joint-administrator David Whitehouse said: "We are very pleased to announce that to date we have received several indicative bids for Rangers Football Club.
"We believe the level of interest in purchasing the club from around the world reflects the pedigree and history of the club and the fact the financial position of the business is beginning to clear and will continue to do so over forthcoming weeks.
"However, it is evident from our preliminary assessment of the expressions of interest and indicative bids that prospective purchasers are looking for clarity on certain issues at the earliest possible opportunity prior to submitting more detailed formal bids.
"There are complex issues to be resolved and there is no doubt they are having a bearing on the bidding process. At this stage we have indicative and conditional bids only.
"Our next step is to review more thoroughly the bids we have received and to determine which could offer the best return for creditors.
"We will also consider the terms and conditions that any party has attached to their bid.
"This process will involve further discussions between ourselves and interested parties and will begin early next week with a view to clarifying the content of each offer.
"The key element of the bidding process thus far has been to give prospective bidders the opportunity to demonstrate their funding capability.
"We cannot, under our remit, exclude the possibility of a bid by any other party and interest was expressed by a party today suggesting a bid will be made over the weekend."
