"A quick reminder for the NHL trade deadline on Friday.
A team wanting to make one of its players eligible for the AHL playoffs must demote its player on Friday. The team can immediately recall him, but this will consume one of its 4 regular recalls available until the end of the season. This situation applies to any player recalled during the season from Laval, such as Joshua Roy and Jayden Struble. Last year, the Canadiens used this strategy in the cases of Corey Schueneman and Rafaël Harvey-Pinard. Both were thus able to play in the Rocket's playoffs.
If a team, due to injuries, finds itself below the minimum number of available players at each position, an emergency recall remains possible and will not count towards the number of emergency recalls.
For players requiring waivers, the same principle applies, except that the player in question must be submitted the day before so that the 31 other teams can claim him if they wish. The player can then be demoted the next day. For example, Alex Belzile was not submitted for waivers the day before the deadline last year, so it was immediately clear he would not return to Laval."
