Anaheim Ducks forward Rickard Rakell will be off skates for at least two weeks.
The club announced the 23-year-old underwent surgery to remove scar tissue relating to his appendectomy in the spring.

Rakell was replaced on Sweden's World Cup roster by Patrik Berglund earlier in the week, after he was hospitalized with a stomach virus.
A first-round pick in 2011, Rakell scored 20 goals - a career high - in 72 games last season.
