John Guidetti scored and was then sent off as Feyenoord were held by RKC Waalwijk, while VVV Venlo secured an important win at De Graafschap.
Feyenoord's bid for the title suffered a dent following a 1-1 home draw with RKC, who capitalised on playing the closing stages against 10 men by scoring a late equaliser.
On-loan striker Guidetti, who has been in stunning goalscoring form for Feyenoord, finally made the breakthrough from the penalty spot with 13 minutes left.
However, Guidetti was shown a second yellow card for taking off his shirt in celebration and RKC took advantage to level with three minutes to go through Robert Braber.
VVV produced a stunning second-half performance to boost their own survival prospects with a 4-1 victory away at bottom club De Graafschap.
Rydell Poepon had given De Graafschap a 13th minute lead, but VVV equalised five minutes into the second half through Danny Holla.
Just two minutes later, VVV were ahead courtesy of Maya Yoshida before further goals from Uche Nwofor and Steven Berghuis wrapped up a fifth league win of the season.
Second-bottom Excelsior came from behind to claim a 1-1 draw away to ADO Den Haag thanks to Roland Alberg's equaliser.
Alberg's goal four minutes after half-time spared team-mate Edwin de Graaf's blushes after his own goal had given Den Haag a 35th minute lead.
Heracles Almelo came from behind to beat Roda JC Kerkrade 2-1 at home to move to within a point of their opponents.
The visitors took the lead five minutes before half-time through Sanharib Malki, but Ramos da Silva equalised on 65 minutes.
Willie Overtoom then scored a 78th minute winner for Heracles after Roda JC had seen goalkeeper Pavel Kieszek sent off.
