The NHL suspended Westgarth on Tuesday for the incident that occurred at 7:55 of the first period of Carolina’s 4-1 victory over the Senators on Sunday.
Westgarth was penalized two minutes for a dangerous check from behind, hitting Borowiecki as the Ottawa blue-liner tried to regain his footing and control of the puck after falling while carrying the puck behind his team’s net.
Borowiecki left the ice under his own but did not return to the game.
Westgarth, who has zero points and a minus-2 rating in eight games this season, will forfeit $7,435.90 US in salary under the collective bargaining agreement that will be directed to the Players’ Emergency Assistance Fund.
Carolina and New Jersey are tied for fourth place in the Eastern Conference’s Metropolitan Division with 23 points apiece.
