Chris Pronger is probably done. That is unless he becomes symptom free for several months and takes a lot of time to get into game shape. Chances are good if he ever recovers it won't be 100% and he'll miss all of next season.
As much as I'd like to have a healthy Chris Pronger in our lineup, it really is a shame that he's still experiencing symptoms in his day-to-day life, let alone not being able to play hockey. It just really really sucks.
