After 21 minutes, experienced defender Mette Tranborg limped off the court with what looked like a sprain or torn ligament.
If it's the latter, she will certainly be ruled out for the upcoming World Cup. Assistant coach Bojana Popovic could not or would not say much about the injury and its extent during the interval.
"We don't know yet. We'll have to look into it after the game, then we might find out. Maybe tomorrow", she told TV 2 Sport.
Another of the national team's experienced defenders is also struggling with his fitness.
Line Haugsted has an arm injury and sat out the match against Sweden. She will not be in action in the rematch against the Swedes on Saturday either.
"It looks promising, but we are fighting against time. We don't feel uncertain but whether she will reach full fitness by the start of the World Cup, or when it will be, is too early to say. We are fighting for it and betting on it and are positive", says the national team's physiotherapist, Mikkel Hjuler, to TV 2 Sport.
In the goalkeeper position, there is uncertainty about Althea Reinhardt, who has knee problems.
Earlier this week, Helle Thomsen called up Amalie Milling to the World Cup squad.
"We still hope that she (Reinhardt, ed.) can be ready during the final round, and that is why she is still part of the squad as it looks now, says Helle Thomsen.
At the end of October, key playmaker Mie Hojlund broke a bone in her lower leg and will also not be fit for the World Cup.
Denmark play their first match in the World Cup against Japan on 27 November.
