Treliving added that the surgery will require significant rehab but said a timeline for his return to the NHL won’t be provided right away.
“We’re not necessarily focused on time frames right now,” Treliving said. “This is months not days or weeks.”
The Maple Leafs announced in July that Murray would begin the season on long-term injured reserve but no specifics about the injury have been disclosed.
Murray is entering the final season of his contract with the Maple Leafs but had fallen down the depth chart after missing time with abductor, ankle and head injuries in 2022-23.
Treliving also said that defenceman Jake Muzzin will remain unavailable to the team this season. Muzzin, 34, only appeared in four games last season due to a back injury and has a history of concussions as well.
