What happened: Forward Josh Anderson will miss approximately three to four weeks due to a lower-body injury, having returned to the lineup on Nov. 10. Defenseman Mike Matheson is also sidelined for approximately two to three weeks with a lower-body injury.

Why it matters: The simultaneous absences subtract a veteran forward and a regular blue-liner from the rotation. Both players face multi-week recovery timelines during the November regular-season schedule.

What to watch: Montreal faces corresponding roster adjustments to fill the open forward and defensive spots.
