Five season-defining matches will take place over a three-week period, with all games shown exclusively live by BT Sport.
In the first Vanarama Eliminator, rivals Notts County and Chesterfield battle it out next Saturday afternoon before the winner faces Gary Johnson's Torquay the following weekend.
