The Bruins challenged Auston Matthews' go-ahead goal with just over eight minutes left in the game for goaltender interference after Leafs forward Zach Hyman appeared to make contact with Tuukka Rask. The goal was upheld, and Bruins head coach Bruce Cassidy disagrees with the decision.
"From my viewpoint it clearly looked like goaltender interference," Cassidy said postgame, according to The Athletic's Joe McDonald. "The call didn't go our way and it's 1-0 with eight minutes to go. We have time to get ourselves back in the game and regroup, unfortunately we weren't able to do that."
Hyman, who was jockeying for position with Bruins defenseman Charlie McAvoy and backed into Rask accidentally, holds a different opinion.
"I was battling in front and I might've got bumped into him, but I don't think it caused much of anything ... I thought it was a good goal," Hyman said, according to TSN's Mark Masters.
In its explanation, the league said the review was inconclusive and the call on the ice was confirmed.
Maple Leafs speedster Kasperi Kapanen added another goal just over two minutes later that stood as the game-winner.
Toronto can eliminate the Bruins at home in Game 6 on Sunday, and also secure the franchise's first playoff series victory since 2004.
