Robertson underwent foot surgery to remove a cyst this offseason and will miss preseason games, Lia Assimakopoulos of The Dallas Morning News reports.
Robertson is expected to be healthy in time for the Stars' first game of the year Oct. 10 versus the Predators. His absence should provide an opportunity for multiple players to audition for a top-six role, including rookies Logan Stankoven and Mavrik Bourque, though both may ultimately end up on the third line to begin 2024-25.
