The Calgary Flames and general manager Brad Treliving have agreed to end his tenure, the club announced Monday.
Don Maloney will take over as president of hockey operations and interim GM. The 64-year-old had been the team's senior vice president of hockey operations.
Treliving's contract expires June 30. The Flames hired the 53-year-old in April 2014. He was the assistant GM of the Arizona Coyotes under Maloney, who Treliving later hired to the Flames' front office as a pro scout.
