The Pittsburgh Penguins announced the firing of assistant general manager Jason Karmanos on Monday and added former defenceman Trevor Daley to their staff as a hockey operations advisor.

Karmanos, the son of former Hartford Whalers/Carolina Hurricanes owner Peter Karmanos, had been with the club since 2014 and had also served as the general manager of the team's American Hockey League affiliate Wilkes-Barre/Scranton Penguins.

"We would like to thank Jason Karmanos for his contributions to the organization over the past six years," Penguins GM Jim Rutherford said in a statement. "I have been evaluating our hockey operations department, and this is the first part of the process to re-organize our group."

With the dismissal of Karmanos, the team announced further restructuring. Sam Ventura, the Penguins' director of hockey research, is set to assume Karmanos's duties, while Erik Heasley, the club's manager of hockey operations, takes over as AHL GM on an interim basis.

Prior to joining the Penguins, Karmanos had served in a number of roles with the Hurricanes, including assistant GM and executive director of hockey operations.

Daley, 37, will report directly to Rutherford, assisting in player evaluations at the NHL and AHL level, as well as acting as an 'eye in the sky' for the coaching staff during games, the team said.

"First, I would like to congratulate Trevor on an incredibly successful 16-year career," said Rutherford. "In addition to being a Stanley Cup Champion with us, he left us with a great impression due to his professional demeanor and quiet leadership qualities. Those traits, along with his desire to want to learn about the business side of the NHL, made him a great candidate to join our staff."

As a player, Daley appeared  in 1,058 games with the Dallas Stars, Chicago Blackhawks, Penguins and Detroit Red Wings. He posted 89 goals and 309 points over his career and won back-to-back Stanley Cups with the Penguins in 2016 and 2017.
