So, the question is : why wasn't it challenged by Mike Yeo? The official told him that this sequence wasn't reviewable, even if it was, under the "play stoppage" rule implemented after the Karlsson goal during the 2019 Stanley Cup Playoffs series between the San Jose Sharks and the St. Louis Blues.
It's honestly embarrassing. After the game, Mike Yeo told reporters that he just didn't want to go back to this sequence. And he's right. What's done is done, but the referees should know the rules of the game.
