Sawada was carrying the puck into the Bruins' zone midway through the second period when Paille hit him. Sawada left the ice under his own power but did not return to the game. Paille was given a five-minute penalty for an illegal hit to the head, as well as a game misconduct.
"Paille delivered a lateral hit where the principal point of contact was his opponent's head," said Senior Vice President of Hockey Operations Mike Murphy. "Additionally, the injury suffered by the Dallas player was a factor in this decision."
The incident occurred at 8:39 of the second period and Paille was assessed a major penalty and game misconduct under Rule 48 for Illegal Check to the Head.
Paille's fine is based on his average annual salary and is calculated under the terms of the Collective Bargaining Agreement. The money goes to the Players' Emergency Assistance Fund. He will miss the Bruins next four games -- Feb. 5 vs. San Jose, Feb. 9 vs. Montreal, Feb. 11 vs. Detroit and Feb. 13 at Detroit. He is eligible to return Feb. 15 vs. Toronto.
