Heiskanen is expected to miss extended time with a knee injury suffered Tuesday night against the Golden Knights.

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

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.
