Murphy left Thursday's game after being hit by Alex Ovechkin and did not return. Murphy suffered a concussion on the play and is in concussion protocol, which likely rules him out of the Blackhawks' back-to-back over the weekend.
Stillman has missed the last three games with a knee injury but will be a game-time decision in Washington. Stillman would replace Calvin de Haan (back) if he were to play.
Brown returned to the lineup on Monday but played just 2:35 TOI before departing with an upper-body injury. Brown will be out until after the Christmas break and could be sidelined until mid-January.
Stillman suffered a left knee injury early in Sunday's win over the Canucks and his designation for IR means he'll miss at least the next three games. Wyatt Kalynuk was recalled from the AHL to take Stillman's spot on the roster in Calgary.
Janmark missed the morning skate but the Golden Knights are optimistic that he will play vs. the Blue Jackets. Janmark has been quiet so far this season, picking up just two assists in 12 games.
