The star defenseman will likely be out for months, if not the rest of the season. Expect the Stars to struggle in his absence, and to have a much better understanding of their roster when he returns.

Stars defenseman Miro Heiskanen is week to week with a lower-body injury, and the standout from Finland won't play in next month's 4 Nations Face-Off tournament.

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, head coach Peter DeBoer announced on Thursday.

Defenseman Miro Heiskanen was injured in the third period of the Dallas Stars’ 4-3 overtime victory over Vegas after taking a hit from Golden Knights captain Mark Stone.

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.

In the third period of a tight contest, Stone was tripped by Stars forward Roope Hintz, causing him to lose balance. As he fell to the ice, he took out Heiskanen’s leg. The blue liner immediately grabbed his left knee and was in visible pain as he headed towards the tunnel with the help of his teammates.

The former Ottawa Senators star was ripped on social media after colliding with Miro Heiskanen's knee on Tuesday night.
