It is time to believe in miracles for Leicester City fans.
Nigel Pearson's men go to arch-rivals Nottingham Forest and have to win – something they have not done since 1972 more than 40 years ago.
They then have to hope that in-form Bolton get no better than a draw at Blackpool, a team with nothing left to play for this season.
Add in a sell-out crowd of more than 30,000, a derby against Forest and City captain Wes Morgan's return to the City ground, and it could not be a much bigger game.
One City player well aware of the importance of the game is long-serving midfielder Andy King.
He said that not reaching the play-offs today will mean the season must be viewed as a failure.
King said promotion had been the target from the opening day, and he believes City can get the result they so desperately need at the City Ground.
"If things don't go our way, the season will have to be viewed as a failure," said King.
"We've always set out to get promoted this season. If that doesn't happen, we won't have reached our goal and that is something we would need to address.
"I don't think we have a fear of failure but as a player I want to be in the Premier League and as a club that is where we want to be.
"The club is geared up to be there, we have the fans and infrastructure to make it happen. It's all down to this game.
"I've seen progress this season but we need to get over the finishing line. We don't want to waste the season. Having looked so good for two-thirds, we don't want it to finish now."
Forest grabbed a point at the King Power Stadium earlier in the season and City have not forgotten the controversial penalty decision which denied them two precious points.
"We maybe owe them one for that," said King.
"The form guide goes out of the window with one game to go. It's like a cup final now, we just need to go out and give it our best like we know we can."
Here's what the teams need to do to make the final play-off spot Leicester City: Have to beat Forest and hope Bolton fail to beat Blackpool. Bolton: They have to better the result of either City or Forest. If Bolton and Forest both draw, Dougie Freedman's men make it on goal difference. Forest: They have to better Bolton's result but will also overtake Palace if Forest win and Ian Holloway's side lose. If Palace draw, Forest need to beat City by more than five goals!
