It is the Pittsburgh club that writes about the Swede's fate and that the forward will be out for at least three months.
Given the time away from the ice, the 25-year-old will miss the games against Nashville in Stockholm, on November 14 and 15.
Hållander left SHL team Timrå after last season and has had a good start with the Penguins. In 13 games, he has scored one goal and four points, and averaged 13.09 minutes of ice time per game.
