Stags would end their relegation season with a 2-1 win over Northampton Town in front of just 3,928 fans.
Goals from Andy White and a late Liam Lawrence penalty took the victory.
The League was known as The Second Division back in those days and saw Huddersfield Town and Cheltenham Town join Stags and Northampton in going down.
That year Wigan Athletic and Crewe Alexandra sealed automatic promotion, with Cardiff City going up via the play-offs.
Here is the side that started the game that day and what happened to them following relegation.
