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, and the standout from Finland won't play in next month's 4 Nations Face-Off tournament.

Bad things happen in hockey sometimes, and it's nobody's fault. That sure looks like what happened in the Stone and Heiskanen incident, says Ken Campbell.
