Blues forward Oskar Sundqvist will miss the rest of the 2020-21 NHL season with a torn ACL in his left knee that requires surgery.

Sundqvist was helped off the ice in the Blues’ 2-1 win Friday after a collision with teammate Kyle Clifford, whose knee hit Sundqvist in the back of the left leg and caused him to fall on the ice. Sundqvist was unable to put any weight on his left leg when he left Friday’s game.

The Swedish forward had four goals and five assists in 28 games prior to his injury.
