"Unfortunately, Mattias has a ligament injury in his ankle and will be out of hockey for a while.
The preliminary assessment of his rehabilitation is 6-8 weeks," says Jonas Kalman, team doctor in HV71 to the club's website.
32-year-old Tedenby has started the SHL season sluggishly and has gone scoreless from all five games.
HV71 is in turn second last in the table after only one win in five games.
