Colorado Avalanche forward Mikko Rantanen left the team's game against the St. Louis Blues early Monday night with a lower body injury.
The team announced he would not return to the game.
The injury occurred in the second period when Rantanen was skating back into the neutral zone and his left skate caught the ice, having his ankle turn sideways.
The 22-year-old needed help getting down the tunnel to the dressing room.
The Finnish forward has 11 points in eight games to open the 2019-20 season.
He enters this season fresh off signing a six-year $55.5 million contract.
