TAMPA — The Lightning reassigned Cory Conacher to AHL Syracuse on Wednesday before he could even play a game on his callup.The forward was recalled Tuesday as insurance with Alex Killorn unable to play against the Predators that night with a lower-body injury.Conacher’s return is a good sign for Killorn’s status but disappointing for a player who has been up and down like a yo-yo this month. The Lightning’s next game is Thursday against the Wild at Amalie Arena.
