If i recall last night (things got a little blurry after Florida got their first goal), Josi got sent head first (like top of the head) into the boards. Was extremely slow to get fully back onto his feet and then took a shift or two before never returning.
Given his injury history, they may of just been cautious. Also, his history of concussions doesnt leave me optimistic. If he is indeed concussed, shut him down for the rest of the season. Call up Gravel (please dont subject Stastney to this) or pick Dermott up off of waivers. The team is cooked for the season.
