Canes coach Peter Laviolette said defensemen Dennis Seidenberg and Tim Gleason, and forward Scott Walker were doubtful for Sunday's game against the Anaheim Ducks.
Seidenberg suffered an undisclosed lower-body injury during the Canes' 3-2 overtime win Friday at Philadelphia. He did not play in the third period or overtime.
Walker was injured against the Flyers on Wednesday and apparently has a groin injury. Gleason has missed the last three games with a leg injury.
Forward Justin Williams, out all season after an Achilles tendon tear in September, continues to skate with the team in practice and may be close to returning. Ray Whitney missed practice today but will play against the Ducks, Laviolette said.
