Ajax missed out on the chance to go top of the Eredivisie by drawing 1-1 with ADO Den Haag in this afternoon's match at Kyocera Stadion.
The visitors took the lead in just the eighth minute when Davy Klaassen fired home from Ricardo Kishna's cross.
It looked as though that would be enough for a win which would put the pressure on PSV Eindhoven until Michiel Kramer's 85th-minute strike earned ADO a point.
There were unsavoury scenes in the fifth minute of injury time which resulted in ADO's Gianni Zuiverloon being sent off.
Ajax stay second, a point behind PSV, who can go four clear if they beat Feyenoord later today.
