Philadelphia Flyers coach Alain Vigneault has pushed back against accusations made by Vegas Golden Knights goalie Robin Lehner that appeared to implicate Vigneault and the Flyers in the medical malpractice of players.

Lehner posted a series of tweets on Saturday about the treatment of players by NHL teams in an effort to bring attention to the stalemate between the Buffalo Sabres and Lehner's former teammate Jack Eichel over his surgery options.
