- Such injuries testify that the balance in rehabilitation and training is not optimal. She has been in a rehabilitation phase and when the load increases again, you become vulnerable to such injuries, says Norwegian national team doctor Öystein Andersen to NRK.

And now he expects Flugstad Östberg to be gone for a longer period - again.

- In principle, she will be gone as long as last time. That is, a couple of months, Andersen continues.

Flugstad Östberg itself is depressed after the new injury.

- It is of course very boring, and I will do what I can to get through this. The balance between training, rest and nutrition has not been optimal, says Flugstad Östberg in a press release from the Norwegian Ski Association.

29-year-old Ingvild Flugstad Östberg previously has two Olympic golds, a World Cup gold and a total victory in the Tour de Ski on the merit list.
