She was bad on the World Cup in Oestersund, and was replaced by Johanna Skottnheim.
Stina went to conquer the weaker IBU Cup, and Johanna Scottheim took her place, but didn't last long. The final 61st place in the sprint and not getting into the pursuit, and now the coaches decide that it is better to use Stina again. At the IBU Cup, Stina took 19th, 26th and 16th places, which is generally not a good result for someone who wants to compete in the World Cup.
But Johanna Scottheim doesn't go to the IBU Cup, and neither the coaches nor the federation comment on why, and what about Johanna.
One more replacement in the Sweden team - Malte Stefansson returns to WC, Oskar Brandt - goes to IBU.
