Pyyhtia was called up from AHL Cleveland on Wednesday.
Pyyhtia saw action in 47 regular-season games last year, generating four goals, three assists and 25 hits while averaging 12:06 of ice time. Even with his promotion to the NHL roster, the winger is far from a lock to play and would need to edge out the likes of Zach Aston-Reese, Brendan Gaunce or Danton Heinen.
