Karlsson (lower body) will be activated from long-term injured reserve ahead of his return to the lineup in Game 1 against Anaheim on Monday.
After being limited to only 14 appearances during the 2025-26 regular season, Karlsson could occupy a middle-six role in Vegas' second-round playoff series against the Ducks. He had four goals, seven points, 30 shots on net and 13 blocked shots before getting hurt.
