Tomasino was placed on waivers by the Senators on Sunday, Bruce Garrioch of Postmedia reports.
Tomasino spent most of the 2025-26 campaign in the AHL, where he recorded 12 goals and 29 assists across 52 regular-season appearances between Wilkes-Barre/Scranton and Lehigh Valley. He'll presumably head back to the minors if he clears waivers.
