For Pollock, the worst part about this is that he will not be able to retire the way he wanted to. Typically, NHL referees are allowed to dictate their final match. The only rule is that it must be a regular season game. The retiring official is allowed to pick the game and the rest of his crew.
Luckily for Pollock, this will not be his last chance to officiate hockey games. Since suffering the injury, he has joined the PWHL, helping run their replay review room, similar to the situation room in Toronto that NHL fans complain about so often.
Pollock officiated in more than 1600 career regular season NHL games and more than 200 playoff games. In fact, he's 6th all-time in NHL playoff games officiated. The fact that he's been in so many games and is not a well-known official by name is an indication of how good he was throughout his career. The NHL will surely miss having him in their games.
