The NHL and NHLPA announced several new protocols on Thursday after COVID-19 outbreaks on five teams caused nearly a dozen games to be postponed this week. The enhanced measures, endorsed by league medical experts, will be in effect until at least Feb. 28 and could feature further restrictions.

The Buffalo Sabres, Colorado Avalanche, Minnesota Wild, New Jersey Devils and Philadelphia Flyers all have multiple players on the league's COVID protocol related absences list, and have had multiple games postponed.
