Elvira Öberg has been Sweden's best biathlete this winter, and is second in the overall World Cup.
But she will not be on the Swedish team when the ladies go relay.
"Elvira does not feel 100 percent and will not go today," writes national team manager Johannes Lukas in a statement.
Linn Persson healthy again
The replacement will be Linn Persson, who sat out the distance race the day before yesterday, when she felt smelly.
"She trained yesterday and feels good again," writes Lukas.
Sweden leads the relay cup
The other distances are taken by Mona Brorsson, Anna Magnusson and Hanna Öberg.
Sweden leads the relay cup in the World Cup, after a victory and a second place in the season opener.
