Cheltenham kept their survival hopes alive going into the final day of the League One season after a 2-0 home win over promotion-chasing Peterborough.
First-half goals from Joe Nuttall and Matty Taylor took Town, in the final relegation place, two points behind Burton.
With their play-off spot already secured, Posh boss Darren Ferguson rested a host of regulars, making seven changes.
And his youthful side were blown away in the first half by the Robins, who knew anything other than a win meant relegation with one game to play.
Nuttall reacted quickest to bundle the ball over the line from close range after goalkeeper Nicholas Bilokapic could only parry Liam Sercombe’s shot in the 11th minute.
The lead was doubled 10 minutes later when Taylor brought down a ball forward from Lewis Freestone and applied an expert finish.
Taylor crashed a shot against the post in the 32nd minute after Liam Kinsella’s pass and Elliott Bonds forced Bilokapic into a smart save two minutes later.
Posh threatened through Ricky-Jade Jones before half-time, but they were second best and Taylor and Bonds both forced Bilokapic into evasive action in the second half.
At the other end, Luke Southwood parried Jonson Clarke-Harris’ shot in the 58th minute and kept out a late header from the centre forward.
Cheltenham must beat Stevenage on Saturday and hope that Burton fail to win at Fleetwood and or Cambridge lose to Port Vale, if they are to escape the drop.
