Top defenseman Miro Heiskanen and prolific forward Jason Robertson, their leading goal scorer in the regular season, missed the seven-game series against Colorado because of lower-body injuries.

DALLAS – Jason Robertson and Miro Heiskanen, who each missed the entire Western Conference First Round for the Dallas Stars, are expected to return from injury in the second round, though coach Pete DeBoer is not certain when that will be.

Through six games against Colorado, it remains to be seen. In a thrilling back-and-fourth series with two ties and both teams leading at different points, the Stars have surprised the hockey world by reaching Game 7 in a series many counted them out of because of Heiskanen’s — and Jason Robertson’s — absences.
