Sandra Näslund leads the overall world cup in ski cross with her seven world cup victories this season.
This weekend, she took two new ones in Canadian Nakiska.
In the same competitions, Fanny Smith finished second and third, respectively.
Smith is chasing almost behind in the overall world cup and has for several seasons been the Swede's biggest threat.
Now the Swiss have injured themselves.
After a crash this weekend, she was examined in her home country, it was revealed that one knee is injured.
"Since returning from Canada, I have undergone a number of medical examinations that have shown an injury to my knee.
The healing process will need to be evaluated day by day.
Unfortunately, this means that I will not be able to compete in Idre this weekend ", she writes on Instagram.
With only a few weeks left until the peak of the season, it is therefore justified to ask whether the Olympics are in danger?
"Now can be sure of one thing - my goal is still to be at the Olympics in Beijing."
SVT Sport has contacted Sandra Näslund for a comment.
