On Friday, April 1, the Flames returned Brett Kulak, up on emergency recall, to the Stockton Heat. Kulak last played on March 30, against the Anaheim Ducks, before Jyrki Jokipakka returned to the lineup.
Now, Emile Poirier has been returned to the AHL. Poirier, also previously up on emergency recall, also last played on March 30, before Johnny Gaudreau returned to the lineup.
This leaves Hunter Shinkaruk, who was recalled at the same time as them, still up in the NHL. Michael Frolik is the Flames' lone injured player, but we don't know just what the extent of his injury is.
