Dolberg, who started a second period at Ajax a year ago, has been struggling to make an impact at the Amsterdam club. In contrast, he has been in good form for Denmark, scoring three goals and providing three assists in nine games over the summer. The Danish team, which missed out on the World Cup last year, begins their Nations League campaign on Thursday with an away match against Norway. They will also face Wales and Portugal in Group A.

The injury is a significant blow to Denmark's preparations for the Nations League, with Dolberg set to miss a longer period of time. The Danish Football Association has confirmed that he will be sidelined for an extended period.
