The 20-year-old prospect was treated on the field after collapsing during Ajax's game against the German side, which was abandoned
Ajax player Abdelhak Nouri received treatment on the field after collapsing during Saturday's friendly against Werder Bremen in Austria, with the Eredivisie club later clarifying he had suffered a heart arrythmia but was in a stable condition.
In the 72nd minute of the game at Lindenstadion in Hippach, the 20-year-old midfielder lay down on his back inside the Bremen half in clear discomfort.
Ambulances and paramedics then tended to Nouri on the pitch, with a screen drawn around him.
