Ricky van Haaren's stoppage-time goal has seen already-relegated Dordrecht sign off their Eredivisie campaign with a 2-1 win against second-placed Ajax.
The Amsterdam giants started brightly, with Anwar El-Ghazi missing an early chance to put them ahead.
Ajax did make the breakthrough on 57 minutes when Danish midfielder Viktor Fischer found space in the Dordrecht box before stroking the ball into the bottom corner.
However, they were pegged back with 20 minutes left as Sean Klaiber turned Joris van Overeem's cross home to give the bottom side hope of a shock victory.
Arkadiusz Milik tried to restore Ajax's lead late on, but was denied with a free kick before Dordrecht completed their comeback.
The hosts scored their winner in the first minute of stoppage time as Van Haaren's free kick proved to good for Diederik Boer to keep out.
