It's unclear what this means for the status of Jake Allen or Samuel Montembeault but Primeau will likely backup regardless of who is ailing. Primeau is 8-6-1 with a 2.77 GAA and .912 SV% in 16 AHL games this season.
Anderson's original timetable was 2-to-4 weeks but has been downgraded. Anderson will likely be out until at least the end of January/early February.
Gallagher has been out since November 29th but could return by this weekend. Gallagher won't re-join the team immediately, which suggests he won't play Thursday vs. the Flyers and is more likely for Saturday vs. the Bruins.
Evans missed Saturday's game in St. Louis but was on the ice for Monday's practice and could play Tuesday. However, he remains questionable, so monitor his status as the Canadiens hit the ice for warmups at 6:30 PM ET.
Laine has been out since November 3rd but appears close to returning to the lineup after joining the team in Vancouver. It's unclear whether or not he is ready to play Tuesday but travelling is a great sign for Laine.
Evans is day-to-day with an undisclosed injury, so he'll come out of the lineup in St. Louis. Joel Armia is expected to return to the lineup to replace Evans.
Gallagher is doubtful to be in the lineup on Thursday after being moved to the COVID-19 protocol list this morning. With Gallagher likely out, look for Cedric Paquette to draw back into the lineup.
Carrier has missed the last three games with an upper-body injury but will play Saturday in Montreal. Carrier has scored one goal with four assists (five points) in 13 games this season.
Caufield struggled with the Canadiens early in the season, failing to score a goal with one assist in 10 games. He went to Laval and picked up five points (2G / 3A) in six games. He should be plugged directly into the lineup Thursday vs. the Penguins.
Carrier was forced to leave Wednesday's game after getting hit in the head by a Tyler Seguin shot. Head coach John Hynes said that Carrier was "up and moving about" and travelled with the team to St. Louis last night. He'll be evaluated ahead of Thursday's contest.
Anderson was not on the ice for Tuesday's morning skate and will be a game-time decision vs. the Kings due to a non-COVID-19 related illness. Expect Adam Brooks to replace him in the lineup if he can't play.
