Whatever the results elsewhere on this coming Saturday, the B2net Stadium will witness a relegation.
The Spireites, seven points from safety with three games left, host Rochdale, who are one point worse off.
Dale have to win all of their remaining games to stand any chance of retaining their League One status, so a draw or a defeat will condemn them to a return to the basement.
John Sheridan’s Chesterfield could hang on for a bit longer with a draw, but only if either Walsall, who travel to relegation-threatened Exeter City, or Leyton Orient, hosts to Yeovil Town, lose. A home win could also see Spireites down but only if both of those teams win.
Goals in the second half from Danny Whitaker and Jordan Bowery at Hartlepool turned the game around for Chesterfield on Saturday and maintained hope of a miracle a little longer.
Neal Trotman (knee) is struggling to be fit to face his former club while veteran Jack Lester (groin) is definitely ruled out.
