Carolina Hurricanes forward Sebastian Aho is out indefinitely with a concussion and a lower-body injury, the team announced on Monday.

Aho was injured on Sunday in a collision with Calgary Flames defenceman Mark Giordano.

The Flames player was assessed a match penalty on the play and ejected from the game, but will face no further discipline as a result of the altercation.

Aho has played in 45 games this season for the Hurricanes and has 16 goals and 21 assists.

The 20-year-old played all 82 games for the Hurricanes in his rookie season of 2016-17.
