Edmonton Oilers defencemen Darnell Nurse and William Lagesson were added to COVID-19 protocol on Monday. 

The Oilers also announced they've closed down the team's training facility until after the holiday break.

Nurse, 26, has one goal and 12 assists over 23 games this season while Lagesson, 25, hasn't recorded a point over seven games. 

The Oilers are not scheduled to play until Dec. 27 against the Calgary Flames after the league shut down cross-border travel until after the holiday break. 

The Ottawa Senators placed assistant coach Davis Payne in the protocol, while the Toronto Maple Leafs added two members of the team's support staff to the list.

The Sens announced Monday that they would not practice until after the holiday break for precautionary reasons. 

The Seattle Kraken also said they have cancelled Monday's practice out of an abundance of caution. 

Seattle is currently scheduled to host the Arizona Coyotes on Tuesday.
