Stars GM Jim Nill on the star defenseman: "As we sit here today, I anticipate him being available sometime during the regular season."

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 defenseman Miro Heiskanen is week to week with a lower-body injury sustained on a big hit from Vegas captain Mark Stone.
