Hatakka was reassigned to AHL Utica on Monday.
Hatakka's demotion could be a sign that Jonas Siegenthaler (concussion) will be ready to play versus the Penguins on Tuesday. The 23-year-old Hatakka has played in 12 NHL contests this season, registering two assists, 14 hits and 12 shots on goal while averaging 14:39 of ice time per game.
