Heiskanen is now the third critical player the Stars have lost for an extended period of time. Tyler Seguin is out for four-to-six months following hip surgery he had done in December, and Mason Marchment has missed a month for face surgery after taking a puck to the face in late December.

Dallas Stars’ head coach Pete DeBoer spoke with reporters on Thursday, revealing that defenseman Miro Heiskanen has been ruled week-to-week with a lower-body injury.
