PSV Eindhoven returned to the top of the Eredivisie but they did so on goal difference only after being held to a 1-1 draw at NEC Nijmegen.
The pressure was on PSV after FC Twente had moved to the summit with victory on Friday and it seemed Marcel Brands' men were on course to regain their two-point advantage when Mathias Jorgensen put them in front in the 10th minute.
But they failed to add to their lead and it came back to haunt them when Victor Palsson struck 10 minutes from time to give NEC a share of the spoils.
Jozy Altidore bagged a brace as AZ Alkmaar ran out 2-1 winners at 10-man Zwolle. The United States striker struck in the second and 34th minutes and although Denni Avdic halved the deficit after the interval, they were reduced to 10 men when Joey Van der Berg was dismissed.
Roda JC moved off the bottom of the table following a goalless draw at home to fellow strugglers NAC Breda. Neither side could find the net but the point ensured the hosts moved above Willem II on goal difference.
There were also no goals between Groningen and VVV-Venlo, where the former were forced to play almost the entire match with 10 men after Leandro Bacuna was sent off in the sixth minute.
