Chesterfield forced a third round replay in the FA Cup after staging a thrilling second half comeback against Scunthorpe United on Tuesday night.
The Spireites trailed at the break at Glanford Park before an Eoin Doyle penalty and a Jay O’Shea goal five minutes from time levelled the scores.
Alex Davey, on loan at the Iron from Chelsea, and a Lyle Taylor solo effort had earlier put Chesterfield’s League One rivals in to a 2-0 lead.
But Doyle’s 22nd goal of the 2013/14 season revived the visitors before O’Shea’s late heroics kept hopes of a fourth round tie away at Derby County alive.
Spireites boss Paul Cook said: “Good teams score late goals. We only needed to get one to give our supporters a massive lift, and that engaged us then to get home.
“The only disappointing thing tonight (Tuesday) is that we felt we deserved more than we got.”
The two teams will meet for a fourth time this season, with a reverse league fixture still to come, at the Proact Stadium on January 13.
Cook will prepare his in-form side before that replay for the visit of Port Vale to the Proact on Saturday (December 10) in the league.
Back-to-back wins either side of Christmas followed by a draw at Coventry City have moved the Spireites within a point of the play-offs at the half way stage.
Port Vale, who Chesterfield overcame 2-1 in the reverse fixture, sit eighth.
