In preparation for their first practice following their bye week on Thursday afternoon, the Montreal Canadiens recalled defenceman Karl Alzner according to the AHL’s transaction page.
The move was expected as the team never formally announced him being sent down. It was effectively a “paper transaction” - a transaction done for administrative purposes without needing the player to report. In this case, the Canadiens have two extra days to send him back down without needing waivers but that seems unlikely at this point.
They would have also saved on their daily cap space, but given the space they have the move was not really necessary.
