The Dallas Stars will be getting a boost to their blue line for Game 1 of the playoffs.
The 26-year-old was injured in a regular-season game against the Wild on April 9 due to a check from Ryan Hartman.
He was forced to miss the Stars’ final three games of the regular season with a lower-body ailment.
Heiskanen had nine goals and 54 assists through 77 games this season.
