According to Elliotte Friedman the NHL and NHLPA have agreed at this time to put in place enhanced COVID protocols until at least January 7th. This date falls 3 days before the NHL must notify the Olympic Committee if NHL players will be made available for the Olympics.
At this time the NHL has no plans to pause the league as a whole and will be managing all outbreaks on a team by team basis. This plan at this time is still for players to attend the Olympics should they so choose.
According to Elliotte Friedman these measures include restrictions on indoor dining while on the road, masking and distancing while in club facilities and daily testing, except on days off.
