The 29-year-old Lupul was in front of the net during a power play midway through the second period when a slapshot from teammate Dion Phaneuf smashed into his arm. Lupul left the game immediately and did not return.
Lupul signed a five-year contract extension with the Maple Leafs on Sunday. He led Toronto with 25 goals and 42 assists last season and made his first All-Star team. Lupul had yet to score for the Maple Leafs this season at the time of the injury.
The groove of being behind a bench is going to be interesting at first, but thank God we have a few exhibition games to get rid of those cobwebs. Overall the excitement of it all and the freshness and coming back refreshed, all those things are going to be assets. If [the players] come ready to give their best effort in practice and games, good things are going to happen. I'm always looking for results. It's not always on the scoreboard. It's winning and building something.
