Cambridge Fans United, the Cambridge Supporters' Trust, are inviting all football fans to the Abbey Stadium for their League Two match against Wycombe Wanderers on Saturday.
Fans from all over the country are being invited to attend the Cambridge game in a bid to raise some funds for the cash-strapped U's, as well as to show solidarity with other financially troubled clubs.
The club are struggling on and off the pitch. They currently sit 92nd in the Football League, are facing relegation to the Nationwide Conference and the loss of vital grants from the Football League.
On the financial front, the club is in dire straits, facing the prospect of not being able to pay its employees beyond the end of February. The Supporters' Trust have set out to rise £500,000 to keep the troubled club alive over the next six months.
Directors of the League Two strugglers sold the Abbey Stadium in November 2004 for £1.9 million to fellow director John Howard's company Bideawhile to clear debts and to provide working capital for the club.
Originally fans were told the money would last for 26 months, but just two months later, the money has run out - largely the result of gross financial misjudgement and a lack of prudence in general over the last three years.
Previous Fans United events have been organised by Brighton, Doncaster and most recently Wrexham when all of these clubs have been in dire financial positions.
Such days have been a significant boost to these clubs and are one important reason why all are still in existence today.
However, not all clubs have been so lucky, Maidstone, Airdrie, Clydebank and Telford have all gone out of business and they will not be the last. CFU are determined to ensure that Cambridge United will not be next on the list.
Football Fans United in Endeavour co-organiser and Cambridge fan Scott Hilsden said: "As soon as the news broke about the club's financial situation fans from Wrexham and Brighton started to organise a trip to the Abbey and fans suggested on the club's official message board that we looked into holding a Fans United Day.
"The support from other clubs has been heartening and we hope to have a fantastic day with as many football fans as possible cheering the U's on."
CFU chair Dave Matthews Jones is also in full support of the Fans United day, saying: "The fans are the future of the club and initiatives such as this prove just that. We will be working flat out to save this club for the fans of tomorrow."
Fans that can't attend are invited to send a shirt, scarf or pendant representing their club to CFU.
