The Bruins' Shawn Thornton has decided to appeal his 15-game suspension for punching and injuring unsuspecting Penguins defenseman Brooks Orpik.
The NHL Players' Association announced it had informed the league of that plan before the 48-hour deadline to do so passed. Orpik was knocked unconscious in the Dec. 7 incident and has not played since because of a concussion.
Montreal Canadiens tough guy George Parros sustained a fighting-related concussion for the second time this season.
Parros was stunned by a pair of late punches in a fight with Eric Boulton in Montreal's 1-0 overtime road win over the New York Islanders on Saturday.
Edmonton Oilers defenseman Corey Potter was suspended for two games for boarding Anaheim Ducks forward Nick Bonino.
