Swindon will be relegated before they come to The Valley if...
Swindon lose at home to Scunthorpe AND Bury draw at home to Northampton OR Port Vale win at home to Bolton OR Port Vale win at Walsall on Tuesday
Swindon draw at home to Scunthorpe AND Bury beat Northampton AND Shrewsbury at least draw at home to Southend OR one of the previous two AND Port Vale take four points from their two games
Swindon beat Scunthorpe AND Bury beat Northampton AND Shrewsbury beat Southend AND Gillingham beat Fleetwood OR two of the previous three and Port Vale win both their matches
Realistically, Swindon are likely to be alive unless they lose to Scunthorpe, although they may need to improve their goal difference for it to be meaningful.
