Feyenoord's on-loan Manchester City striker John Guidetti has suffered an injury to put him in doubt for Sweden's friendly with Croatia on Wednesday.
The 19-year-old, on a season-long loan in Rotterdam, was poised to make his senior international debut after impressing for Feyenoord this season.
However, Guidetti picked up an injury while training with the Sweden squad on Tuesday and is now a serious doubt.
Reports in the Dutch media claimed the striker had twisted his knee and medics suspect a strained muscle.
He will undergo further tests in Zagreb later on Tuesday.
Guidetti told Aftonbladet: "It would be very sad if I missed the match, but it does really hurt."
The teenager has been a revelation at Feyenoord this season, notching 18 goals including three hat-tricks.
The Rotterdammers will be hoping his injury is not serious as they push for a European spot this season.
