AZ Alkmaar moved up to fourth in the Dutch Eredivisie after they drew 1-1 with third placed Feyenoord on Sunday.
Both goals came in the first-half, the first after just four minutes as AZ's young winger Albert Gudmundsson struck.
After Feyenoord's Steven Berghuis gave away the ball, Myron Boadu crossed for Gudmundsson to net his first goal for the club on his first start.
The visitors almost equalised moments after, but Tonny Vilhena's close-range header was saved by the leg of AZ's goalkeeper Marco Bizot.
Just after the half-hour mark, AZ's Boadu went off with what looks like a very serious ankle injury. The 17-year-old striker went down after a challenge from Eric Botteghin and was stretchered off, appearing to be in a lot of pain.
Feyenoord levelled things up in the 34th minute as Berghuis made up for his earlier mistake and slotted past Bizot.
The Rotterdam based side remain third in the table with ten points as AZ move up to fourth, just two points behind.
