I imagine he was injured.. He's definitely got a good year coming up, no reason to bench him. I was at the home opener and he skated on the ice for the introductions (as did every other scratched player) but wasn't really putting any weight on one of his legs and just kinda glided out. I saw him walking around during the game though and I didn't notice a limp or anything.
Whatever the case, he's back now. Played Friday at Guelph and yesterday against Sault Ste. Marie.
