A currently unnamed player has indeed tested positive for COVID, and now the player will be forced to miss at least 5 days on the per league COVID protocol. The Wild are able to call up an additional player regardless of roster restrictions to make up for this absence. However, Russo reports some trouble for the Wild in this case, as they need to ensure the call-up is in Minnesota in time for the flight to Montreal.
Thankfully, it seems this is the first case of COVID in the NHL in a while, and hopefully we rarely see it again. Sporadic flare ups may occur like here in Minnesota, but it seems the days of COVID postponed games are behind us.
