Donington's administrators admit the circuit can forget its Formula One ambitions for now, but are still hoping to imminently sell the long term lease of the Leicestershire venue.
While revealing talks with three potential buyers, administrator Nigel Price said he was disappointed to hear about rival circuit Silverstone's new deal to stage the British Grand Prix until 2026.
"There is a break clause on either side of 10 years, so that closes the door on Formula One at Donington in that time scale," he told the local Derby Telegraph.
"However, we are still in negotiations with three parties with a view to Donington continuing to operate as a national and club circuit.
"We are hopeful a deal can be done by the end of this week," Price added.
