Hildeby stopped 20 shots in regulation and overtime and two of three shootout attempts during Saturday's 3-2 preseason win over the Panthers.
It was a solid showing for the 25-year-old goalie, although neither team was icing its stars. Hildeby is set to open the 2026-27 campaign as the backup to Andrei Vasilevskiy for the Lightning after producing a 2.85 GAA and .912 over 20 regular-season appearances for Toronto last season.
