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 Maple Leafs next play Saturday, when they play their home-opener against the Ottawa Senators (7 p.m. ET, CBC).
Very happy that old guy finally scored. It was great. You see the excitement on his face. I remember when I scored my first goal and it's just such a great feeling. Anytime you can help contribute to a team win it's a lot of fun.
