Boston Bruins coach Bruce Cassidy was fined $25,000 on Tuesday for criticizing the officiating after his team's Game 5 loss to the New York Islanders on Monday night.

Cassidy theorized that the Islanders have fooled the referees into believing they're a squeaky-clean team.

"This is my take on it: We're playing a team that has a very well-respected management and coaching staff. But I think they sell a narrative over there that it's more like the New York Saints, not the New York Islanders," Cassidy said following the Bruins' 5-4 defeat that gave the Islanders a 3-2 lead in the second-round playoff series. "They play hard and they play the right way, but I feel we're the same way. And the exact calls that get called on us do not get called on them, and I don't know why."
