LAS VEGAS — Defenseman Miro Heiskanen was injured in the third period of the Dallas Stars ' 4-3 overtime victory over Vegas on Tuesday night after taking a big hit from Golden Knights captain Mark Stone. Stone fell toward Heiskanen's left knee and thigh after getting tripped.

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

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.

Stars head coach Peter DeBoer told reporters Thursday that Miro Heiskanen has been ruled out week-to-week due to a lower-body injury.
