Before he's pencilled in anywhere from the first to fourth line for the Vancouver Canucks, 21-year-old winger Zack Kassian has to get over a bothersome back that flared up two weeks ago while playing in the AHL. Kassian injured a facet joint, which is any one of four projections that link one vertebra of the spine to an adjacent vertebra.

"I've had some spasms, but nothing major," said Kassian, who has no history of back ailments. "It just takes a little time to heal. Today, I felt good on the ice and it's day by day and I'm on track to be good for training camp. I don't know how I hurt it. I woke up and it was tight and I had another little issue. Skating and playing games probably didn't help, but we've got it solved."
