Feyenoord tumbled out of the KNVB Beker as they were beaten 2-1 at Go Ahead Eagles in their third-round clash.

Go Ahead side took the lead in the seventh minute through Joey Suk and doubled it just before the hour mark courtesy of Marnix Kolder's 59th-minute penalty, meaning Ron Vlaar's 89th-minute strike was too little too late.

AZ Alkmaar narrowly avoided similar embarrassment as they saw off Dordrecht 90 3-2 in extra time.

The top-flight side were 2-0 up through Pontus Wernbloom (45) and Ragnar Klavan (62), but Shayron Curiel pulled one back in the 71st minute and Santy Hulst levelled a minute later.

Adam Maher then netted in the seventh minute of extra time to send AZ through.

In the day's other game, NEC Nijmegen beat FC Volendam 1-0 with Caifano Latupeirissa netting the only goal six minutes before the break.
