Ajax-defender Johnny Heitinga will be out with an injury for at least six months. Heitinga tore the anterior crucial ligament of his left knee in the match against NAC (2-2).
Heitinga replaced captain Cristian Chivu after halftime. Chivu had to be taken off with a bruised rib. It is uncertain whether he will be travelling with Ajax to Norway, where Ajax meet Rosenborg in a Champions League match on Wednesday.
Yesterdays match marked Heitingas return to Ajaxs first team. Last season he spent a long time in rehabilitation from an operation to his right knee.
