Kaskisuo is slated to fill in the backup role behind starter Frederik Andersen after Michael Hutchinson was placed on waivers Monday. The 26-year-old Finland native is 6-1-1 in eight starts with the Marlies this season with a .928 save percentage. He could make his first NHL start as early as Saturday as Toronto travels to Pittsburgh to take on the Penguins in the second half of a back-to-back.
Petan was waived by the Leafs last week but went unclaimed. He returns to the big club in the wake of the recent injury to Mitch Marner, who is sidelined for at least four weeks with an ankle injury.
The 24-year-old has appeared in five games for the Maple Leafs in 2019-20, notching one assist. Petan's also registered seven points in three contests in the AHL this season.
