Sebastian Samuelsson ended the World Cup season in biathlon with a victory in the mass start in Oslo on Sunday.
It was also his last competition for the season.
"I woke up today with a sore throat and unfortunately won't be able to start at the Swedish Championship in Sollefteå", writes Samuelsson on Instagram followed by a sad emoji.
The Swedish Championship in Sollefteå starts today with a sprint and is followed by a mass start on Saturday and a single mixed relay on Sunday.
