Holmstrom (upper body) was designated for injured reserve Tuesday, per Stefen Rosner of NHL.com.

EDGE Analysis

Holmstrom has already missed the required number of days assuming the team used a retroactive designation, so this move shouldn't impact his recovery timeline. Still, it seems unlikely the 23-year-old winger will be in action versus the Knights on Thursday and probably should be expected to miss both legs of the Isles' two-game road trip.
