Gleason signed a professional tryout agreement with the Stars on Wednesday.
Gleason hasn't appeared in an NHL game since he made four regular-season appearances with Dallas during the 2018-19 campaign, but he'll have an opportunity to compete with the Stars during training camp ahead of the 2026-27 regular season. The 28-year-old recorded two goals, 20 assists and 23 PIM across 59 regular-season appearances with AHL Iowa last year, and it wouldn't be surprising to see him spend most, or all, of his time in the minors once again this season.
