Lavoie (undisclosed) is day-to-day, per Danny Webster of the Las Vegas Review-Journal on Monday.
Lavoie sustained the injury in Saturday's 4-2 preseason win over the Kings. He notched 30 goals and 56 points in 45 regular-season appearances for AHL Henderson in 2025-26. To be returned to the minors this campaign, the 25-year-old forward would need to clear waivers.
