Matt Miazga's Eredivisie debut was in relief of Maikel van der Werff during Vitesse's 2-1 loss to Twente on September 25. (You may recall it was the game in which Miazga recorded his first assist in Eredivisie.)
The international break has not been kind to van der Werff: Vitesse's website reports the defender has suffered a knee injury requiring surgery; he is expected to be out of action for six weeks. Nu Sports notes van der Werff's absence will likely see him miss Vitesse's next six league games and a cup match.
