The Rugby Football League have confirmed there are four bids for the Bradford Bulls and they have until next Tuesday to submit their business proposals.
Parties interested in buying the Super League club had until Friday August 10 to make their best offers for the club, who were docked six points for entering administration.
The RFL have met with all the consortia bidding for the Bulls and are 'optimistic' about the future of the beleaguered West Yorkshire outfit.
Chief Operating Officer Ralph Rimmer is unable to disclose to identity of the interested parties, stating only that Super League Europe (Ltd)'s offer still stands.
"We had constructive meetings with all the consortia that have submitted proposals to the administrator and we're optimistic about the future of Bradford Bulls," said Rimmer.
"There are now four confirmed bids for the Bulls and each consortium has been asked to submit business plans to us by Tuesday August 21. Due to the sensitive nature of the current discussions we are unable to confirm who the bids are from at present.
"However, it does appear that this renewed interest has come as a direct consequence of the offer from Super League Europe Ltd, which remains on the table.
"We understand the frustration regarding the on-going process but it is vital that due diligence is carried out on all the bids and that ultimately the right owners are found for the good of the club and the sport as a whole."
The RFL remains in open dialogue with the administrator and the club and will continue to provide what practical support it can.
"We are pleased to be working collaboratively with the RFL to agree on a purchaser and sell the club," said joint administrator Brendan Guilfoyle.
"We now have all the ingredients that the RFL has requested and funds proven from three bidders plus the Super League Europe Ltd offer.
"The RFL will consider the bidders' business plans which are to be received by the Tuesday deadline, and all concerned do understand the need to bring this to a swift conclusion."
