The NHL Department of Player Safety has come to their decision regarding Philadelphia Flyers' defenseman Matt Niskanen's cross check on Montreal Canadiens' forward Brendan Gallagher. 

Gallagher had a CT Scan on his jaw earlier today which showed it was broken and Gallagher will have to leave the bubble for surgery which knocks him out of the remainder of the series because of the quarantine rules. 

Gallagher will need four negative tests in four consecutive days which doesn't make him available for the rest of the series. 

Niskanen has been suspended one game by the NHL which takes him out of Game 6, he will however be allowed to play if there is a Game 7. 

What do you think of the NHL's decision?
