The slumping Carolina Hurricanes say leading scorer Jeff Skinner and key defenseman Joni Pitkanen are out indefinitely with concussions.
General manager Jim Rutherford updated the players' status in a statement issued roughly an hour after the end of Wednesday's practice.
The 19-year-old Skinner leads the team with 12 goals and 24 points and is the NHL's reigning rookie of the year.
He was hit at Edmonton on Dec. 7 and was scratched two nights later at Winnipeg with flu-like symptoms. He was held out of Tuesday night's loss at Toronto after the ailment was recharacterized as an undisclosed injury.
Pitkanen leads the Hurricanes' defensemen with 12 points and nine assists.
The diagnoses are the latest blows to a team that has dropped into last in the Eastern Conference.
