This incident is more of a lowlight than a highlight, but it's big news. It warrants a mention, but I'll rank it No. 10.
The December 7 game between the Boston Bruins and Pittsburgh Penguins spun out of control early. Just 11 minutes, six seconds into the first period, Pittsburgh's James Neal kneed Boston's Brad Marchand in the head while he was down on the ice after a collision with Sidney Crosby.
In the scrum after the penalty call, Boston's Shawn Thornton pulled the Penguins' Brooks Orpik out of the crowd, slew-footed him to the ice, then hit him while we was down. Thornton's actions were intended to avenge a hit by Orpik during the opening shift that knocked Boston's Loui Eriksson out of the game. In this case, frontier justice went way too far.
Status updates on the key characters from the melee: Marchand's not hurt. Eriksson has his second concussion in five weeks. Orpik has been placed on injured reserve with a concussion of his own, per The Associated Press (via ESPN.com). Neal has been suspended for five games, per Joe McDonald of ESPN Boston. Thornton's disciplinary hearing is still to come.
In a separate incident from the same game, Boston's Chris Kelly suffered a broken fibula from a slash by Pascal Dupuis that went unpenalized.
Thankfully, the Penguins and Bruins have now completed their three-game regular-season series, which should allow some time for the dust to settle.
