Seth Jones' Monday night took a turn for the worse.
After notching two points against the Montreal Canadiens, the Columbus Blue Jackets defenseman was forced to leave the game due to an upper-body injury.
It's undoubtedly a tough loss, as Jones leads the Blue Jackets in ice time, averaging nearly 25 minutes per game.
Jones has 48 points in 70 games this season, including four goals in his past three appearances.
