The New York Rangers picked the wrong time to make a line change.
The club conducted a full-scale swap late in the first period, allowing Torrey Mitchell and Shea Weber to walk in on a two-on-one, which they executed to perfection.
The strange play also saw a rarity: six skaters on the ice for both sides.
The tally helped the Montreal Canadiens tie the game at one, while the goal was Mitchell's first of the postseason.
