Kostopoulos, 34, has played 17 games this season for the Penguins' AHL affiliate in Wilkes-Barre/Scranton, tallying three goals and four assists. His assist Saturday against Albany gave him points in four straight games (3g-1a).
The Mississauga native spent last season in Calgary, where he posted four goals and eight assists in 81 games with the Flames. He's recorded 100-or-more penalty minutes in four of his 10 NHL campaigns.
