Spalding United’s fans are being urged to show their full support on Saturday.
The second-placed Tulips face league leaders Shaw Lane who are three points clear with three games in hand.
Boss Dave Frecklington said: “We can’t force people to come out and part with their hard-earned cash as we all understand it costs money to watch football.
“But this is a fantastic occasion for the public to get behind the team in such an important game.
“Hopefully we can get over the line with three points in front of a decent gate.
“The club are building links with the community and this is a big opportunity.”
