Aston Villa goalkeeper Thomas Sorensen has chipped a bone in his finger and is likely to be out for six weeks.
Sorensen damaged the finger during the warm-up before Ebbe Sand's farewell game on Monday evening.
Denmark failed to qualify for this summer's World Cup in Germany but had friendlies against France and Paraguay lined up this month.
"It is a minor, but time-consuming injury, which means Sorensen will have a small protective skin on his finger for the next six weeks," said national team doctor Mogens Kreutzfeldt.
"After that, he will be ready again without any permanent damage."
The injury means Charlton goalkeeper Stephan Andersen will deputise in Sorensen's absence.
Morten Olsen has been keen to give Andersen his opportunity and the 24-year-old will get the chance to prove he is an able replacement for the Villa goalkeeper in the long term.
"It has not been difficult for us to find the replacement for Thomas in this unfortunate situation," Olsen added.
"The choice of Stephan Andersen has been obvious. We know him from his previous work with the national team, and he came back into Charlton's team in late spring. And he is a future man for the national team."
