Veteran striker Tommy Johnson completed a brave Scunthorpe fight-back from two goals down to earn a deserved draw against Chesterfield.
Paul Hall put Chesterfield ahead with his ninth goal of the season and Shane Nicholson doubled the lead from the penalty spot.
Ian Baraclough began Scunthorpe's revival with a shot from 30 yards.
Then substitute Johnson forced the draw after Spireites' keeper Barry Roche parried Neil MacKenzie's shot.
