The NHL is making four changes to its in-arena protocols to help prevent the spread of COVID-19, according to Sportsnet's Elliotte Friedman.

TV viewers will notice the removal of the glass directly behind all team benches. The league is hoping this will increase airflow in an area where players and coaches are close together for an extended period of time.

Additionally, the league indicated it's considering requesting the use of portable air cleaners behind team benches "in order to improve the indoor air quality and mitigate the airborne viral transmission."

Players and coaches can also no longer show up to the arena more than one hour and 45 minutes before puck drop unless they're receiving treatment for injuries. The league advised that all meetings should be held virtually.

Lastly, teams are being asked to use additional locker room space so players are at least six feet apart at their stalls. Facilities that don't have the space are being asked to create it. Portable stalls will be provided if necessary.

The Minnesota Wild were the latest team to have their season halted by COVID-19. Their games are postponed through Feb. 9 after five players landed on the COVID-19 list Wednesday.

The New Jersey Devils have been hit the hardest, as 10 of their players were placed on the COVID-19 list Monday.
