There is a Rovers connection though as Chorley are managed by former Rovers favourites Garry Flitcroft, while another ex-Blackburn star Matt Jansen is player-coach.
Blackburn Rovers FC Action Group has been protesting about the way their club is run by Venky's, who took over at Ewood Park in November 2010.Action group founder Gareth Jones said: "We have got our problems at Blackburn and everything in the Premier League is about money.
"This is a chance to forget about that and see some real football with some real fans."
He said supporters also wanted to show their appreciation for Flitcroft and Jansen for what they did for the club.
An appeal by the group on the website Facebook has also asked fans to back the appeal fund to save Chorley from going into administration. Mr Jones said more than 120 Rovers fans had already said they would attend the Chorley game versus North Ferriby United instead.
He added: "We don't know how many others will be going - it would be great if we could get 500."
Chorley have financial worries after the discovery of a sustantial cash shortfall. A former employee was arrested but no charges have yet been brought pending ongoing investigations by the Police.
Commenting on the potential boost to saturday's crowd, Chorley Chairman, Ken Wright said:
"Obviously we would welcome anything that would increase our home crowd."
But he added: "Obviously we don't want to be involved in the dispute at Blackburn.
"We welcome any support at present - our position is precarious."
Chorley have had some decent gates for the Evostik League this season and had a gate in excess of 1,000 on Boxing Day. The game on saturday is against North Ferriby.
