Tranmere Rovers will be playing in front of their biggest crowd since 2008 when they take to the field against Notts County tonight.
The npower League 1 club offered free admission to the game which was abandoned back in February due a waterlogged pitch.
The final remaining tickets were collected from the Prenton Park Ticket Office on Monday, to make the important clash officially a sell-out.
Chief Executive Mick Horton said: "We've been delighted with the response to our free admission offer following the abandonment of the original game and look forward to welcoming a lot of new people to Prenton Park.
"We're encouraging supporters to arrive early, to be patient as they take their seats and to avoid leaving empty seats between supporters."
A win for Les Parry's side would move them onto 52 points, nine clear of the relegation zone, while a win for County would see them move out of the bottom four and just a place below Rovers in 19th.
A draw would also be enough to move County out of the relegation zone due their superior goal difference compared to Walsall who would slip down.
The Magpies have lost the last nine matches in a row, under three different Managers - Paul Ince, Caretaker Manager Carl Heggs and now Martin Allen but the latter isn't looking at statistics, as he told the Nottingham Evening Post:
"I don't talk about the nine defeats. I will only talk about a good performance against Bournemouth and the players' energy, enthusiasm, desire and willingness to compete. The players did really well, no one can deny that.
"I haven't spoken about relegation or staying up. All I have talked about is playing well and putting in good performances.
"What will be, will be. We will get as many points as quickly as we can and deal with wherever we are at the end of the season."
