Dallas Stars forward Jason Robertson has been ruled out of Game 1 of the Western Conference first-round series against the visiting Colorado Avalanche on Saturday.

Robertson is considered week-to-week due to a lower-body injury he sustained during the Stars’ regular-season finale at the Nashville Predators on Wednesday.

Robertson, 25, led the Stars in goals (35) and finished second in both assists (45) and points (80) while playing in all 82 games this season.

He has totaled 394 points (168 goals, 226 assists) in 374 career games since being selected by Dallas in the second round of the 2017 NHL Draft.
