Williot Swedberg missed Wednesday's training in Valencia with symptoms of illness. A day before Sweden's men's team plays a World Cup playoff semi-final against Ukraine, it is uncertain whether the Celta Vigo striker will be able to play.
"We'll probably have to wait and see regarding Williot. We'll have to decide tomorrow," says Sweden manager Graham Potter.
Gustav Lundgren is also in doubt. The 30-year-old has had injury problems since the beginning of the month and has not played in his last four games.
"We just have to make sure he has had enough training to be ready for the game," Potter said.
If Sweden wins against Ukraine, a decisive match for a World Cup ticket awaits, against either Poland or Albania, at Strawberry Arena in Solna on Tuesday.
