Bradford Bulls' administrators say they expect to make a "significant announcement" about the sale of the club within the next 48 hours after being given until the end of the week to find a buyer or face liquidation.
The crisis-ridden Championship side entered administration for the third time in five years last month and are understood to have debts of well over £1million.
Wages at the club have been paid in full but a number of players are still thought to be looking to quit.
The joint administrators had set a deadline of today for best and final offers to buy the club.
In a statement they said they had received offers from four separate parties, two of which are now subject to a due diligence process.
I am conscious that the sale process has not been as straight-forward as had been originally envisaged. However, I have said throughout that it is crucial we obtain the right deal – rather than the quickest deal – for the club’s future. We have continued to liaise with the RFL.
