Dumba (lower body) was placed on injured reserve Saturday, according to Brian Rea of Bally Sports Southwest.
Dumba suffered the injury a week ago against the Islanders and is considered week-to-week. In a corresponding move, the Stars recalled Matej Blumel from AHL Texas because center Sam Steel (undisclosed) is questionable for Saturday's contest against Edmonton, and Tyler Seguin (lower body) is unavailable.
