In the horizontal shooting, the Norwegian Ingrid Landmark Tandrevold got a boom and went out as ninth - but then she disappeared completely from the results lists.
TV pictures then showed how Tandrevold is lying down in the snow.
And Norway's national team coach Sverre Waaler Kaas can not explain what happened.
"Noticed that something was wrong"
- She got a kind of shock.
She held her breath for a moment on the last shot.
Then she noticed that something was not right up the long hill, so then she had to stop and lie down, Kaas says to NRK.
The national team coach says that the Norwegian was taken by ambulance to the arena.
- Then we will see what we do, says Kaas.
Norwegian Tiril Eckhoff, 30, won the last sprint before the World Cup.
