"Sandra has had surgery before for an anterior cruciate ligament injury in this knee.

In connection with that injury, she also suffered a cartilage injury that has been recalled off and on in recent years," says national team doctor Jakob Swanberg in a press release.

The hope is that Näslund will have time to recover for the World Cup final in Canadian Craigleith next weekend.

Näslund has a streak of 19 straight wins.
