The NHL is relaxing virus protocols during the playoffs for teams that reach a vaccination threshold. The league said Saturday the changes take effect once 85% or more of the traveling party has been fully vaccinated. The new protocols include loosened restrictions on indoor and outdoor dining, testing frequency and mask-wearing and quarantine requirements. The NHL is the last of the major four North American pro sports leagues to announce plans to relax virus protocols for teams based on vaccination levels. This move is likely to affect the 12 U.S. playoff teams first because vaccinations have lagged for those in Canada.
