Chesterfield came from 2-0 down to draw 2-2 at MK Dons after striker Will Grigg scored a dramatic equaliser in the fourth minute of stoppage time.
Goals by Callum Paterson and Rushian Hepburn-Murphy had given the hosts a 2-0 lead at the break, but debutant Sam Curtis pulled one back for the visitors before Grigg's added-time goal salvaged a point for the Spireites. The result pushed Chesterfield into the play-off places in seventh, with MK Dons moving up to fifth before the 15:00 GMT kick-offs.
