According to CSNPhilly.com, Hartnell took a shot off his left foot at 6:53 of the third period and was seen walking gingerly after the game.
If Hartnell, who tied for sixth in the League last season with 37 goals, is unavailable for Thursday's game against the New York Rangers, it could put a struggling team already in deeper trouble. Philadelphia has three goals in three games and entered the season weakened by the offseason departures of James van Riemsdyk and Jaromir Jagr, as well as the wrist injury sidelining Danny Briere.
It's not always going to be pretty, especially against a great goalie [Lundqvist] like that. My goals are never how you draw them up. It's just a matter of grinding it out and trying to create havoc in front and good things happen.
