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 reevaluated in six months, the team said Wednesday.

"It was unfortunate, obviously," Blues interim coach Drew Bannister said Wednesday before the team's announcement was made. "A lot of those injuries are just bad breaks. Unfortunate he got his foot caught there and went into the boards. It's an unfortunate injury for him and certainly we're going to miss him while he's out, but we've got lots of guys capable of filling that role. Guys are going to get more opportunity."

Sundqvist, 30, has recorded 21 points (6 goals, 15 assists) in 71 games this season.

A two-time Stanley Cup winner, Sundqvist has totaled 144 points (56 goals, 88 assists) in 426 career games with the Pittsburgh Penguins, Detroit Red Wings, Minnesota Wild and Blues.
