Tverberg was waived by the Maple Leafs on Thursday, James Mirtle of The Athletic reports.
Tverberg signed a one-year, two-way contract with the Maple Leafs in early July and will head to AHL Toronto for the start of the regular season if he clears waivers. Across 63 regular-season appearances with the Marlies last year, he logged 15 goals, 21 points and 36 PIM.
