No idea actually. Spacek has been pretty banged up lately, there have been several occasions in the last 2-3 games (including last game against TO) where he's been slow to get up after a hit or crash into the boards. Not sure what exactly is wrong with him though.
EDIT: Just heard lower body injury. No specifics other than that.
