Bradford Bulls have revealed the extent of their financial difficulties.
The club need to raise £1m in order to carry on operating, with £500,000 of that amount due by the middle of April.
The Bulls are asking fans to contribute £100 or more each on their official website.
"We've been battling serious financial issues for many years, but with no playoff football for the last three seasons, the biggest and deepest recession this country has experienced in living memory, sponsorship income increasingly difficult to come by - indeed dropping to an all-time low - and our bankers' lack of ongoing support, we have almost reached the end of the line," a statement read.
"The RFL stadium deal only enabled us to address our long-term liabilities but could not help us stave off the grave financial situation we find ourselves in.
"Unlike the majority of other Super League clubs, we have no wealthy benefactor - every penny of income comes from the hard work of the team at Odsal - and the dedication and unrelenting support of people like you."
Bradford Bulls are currently eighth in the Super League.
