St. Louis Blues forward Oskar Sundqvist will miss the remainder of the season after suffering a torn ACL in his right knee, the team announced Wednesday.

Sundqvist was injured after being checked into the boards by Vegas defenseman Brayden McNabb during the second period of Monday's 2-1 overtime loss to the Golden Knights. Sundqvist needed help from his teammates to get off the ice and did not return to the game.

Sundqvist will undergo surgery and be re-evaluated in six months, the team said Wednesday.
