Vlasic (undisclosed) has been ruled out of Sunday's game against the Penguins. Vlasic left Saturday's game against the Flyers with an undisclosed injury, and was ultimately unable to return to the contest. It isn't clear how serious his injury is, but the fact that he has already been ruled out of Sunday's matchup with the Penguins is cause for concern. The team should provide an update on Vlasic's status in the coming days.
