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.

Miro Heiskanen is week to week for the Dallas Stars with a knee injury. The timeline also means the defenseman will likely miss the upcoming 4 Nations Face-Off, with will take place in Montreal and Boston from Feb. 12-20. He had been selected to play for Team Finland along with Stars teammates, defenseman Esa Lindell and forward Roope Hintz.
