Fraser was hit by the Flyers' Jay Rosehill during a third-period scrum that started after Fraser had been called for a minor penalty for high-sticking the Flyers' Zac Rinaldo. After serving the penalty, Fraser left the penalty box and did not return to the game.
The only spare defenseman the Maple Leafs have on their roster is rookie Morgan Rielly, the fifth pick of the 2012 NHL Draft who was a healthy scratch the first two games.
The Maple Leafs next play Saturday, when they play their home-opener against the Ottawa Senators (7 p.m. ET, CBC).
I downplayed the first one because I thought it's just a hockey game. We just want to win the game; it's against our rival and we want the two points. I downplayed it, but now having gone through the first one I look back and say, 'Geez, that was really cool.' I think as I've grown a bit older I've got a lot more appreciation for what we're allowed to do every day.
