Heinen will be placed on waivers by the Penguins, the team announced Sunday.
Heinen's departure from the roster coincides with the return of Blake Lizotte from injured reserve. The 30-year-old Heinen has notched just two points in 13 NHL games this year while averaging 11:40 of ice time per night. If he goes unclaimed, Heinen would report to AHL Wilkes-Barre/Scranton, where he has 17 points (six goals, 11 assists) in 12 games.
