This comes from hockey Insider Frank Seravalli, the NHL is listening to its players and is going make changes teams felt was long overdue.
The NHL was making teams do multiple tests daily but now that alot of players are getting false positives or being asymptomatic, those types of players won't have to be retested.
The NHLPA has been asking for changes to the policy due to the fact alot of players who tested positive have little to no effects from the virus now that players are vaccinated.
