The NHL's Department of Player Safety recently announced a five-game suspension for Brendan Gallagher due to his illegal hit on Adam Pelech from the New York Islanders.
The hit by Gallagher was deemed as intentionally harmful and targeted at Pelech's head, leading to significant consequences.
"Montreal's Brendan Gallagher has been suspended for five games for an illegal check to the head on NY Islanders' Adam Pelech."
Regarding whether the suspension is fair, it's subjective and depends on one's perspective on the severity of the offense and the standards set by the NHL for player safety.
