The exact severity of Hedman's injury is yet to be determined, but it's clear that he's uncomfortable and won't be at 100% capacity. This will certainly affect the Lightning's chances. As for Cernak, his injury represents a significant loss on all levels.
Furthermore, despite the wishes of Toronto fans and the immense pressure he's put on himself by calling his team the "best team in the world," Leafs' head coach Sheldon Keefe has announced that Ilya Samsonov will be the starting goaltender for game two.
