Chesterfield kept their slim hopes of avoiding relegation back to League Two after one season alive by coming from behind to beat Hartlepool.
Gary Liddle turned in Ryan Noble's pass from close range to give Hartlepool a half-time lead.
Spireites substitute Danny Whitaker fired in from 18 yards to level within two minutes of coming on.
And Jordan Bowery completed the fightback when he headed in Scott Boden's cross from close range.
Chesterfield's victory, coupled with Leyton Orient's defeat at Sheffield United, means that they remain seven points from safety with three games remaining.
VIEWS FROM THE DRESSING ROOM
Chesterfield assistant manager Tommy Wright told BBC Radio Sheffield:
"We were poor first half and we never had any great energy about us.
"We never passed the ball well but credit to John [Sheridan]. He made one or two changes tactically and I thought second half we were much better.
"Danny [Whitaker] changed the game when he came on, he was a catalyst for us.
"He got hold of the ball, passed it, took a great shot and improved us greatly."
