Substitute Piotr Parzyszek snatched a late equaliser to earn De Graafschap a 1-1 Eredivisie draw at home to FC Twente on Friday, but it did little to ease their relegation worries.
With his side down to 10 men following the dismissal for two yellow cards of Jeroen Tesselaar, the 22-year-old Pole came off the bench in the 74th minute to score with a low shot four minutes from the end to cancel out Jerson Cabra's first-half strike.
However, the point still leaves them six from safety, having played a match more than their rivals with just three games remaining.
Third-from-bottom Excelsior host Heerenveen on Sunday while Willem II, who are level on points with Excelsior, entertain ADO Den Haag.
