I would hope the news has not escaped you – Google ‘concussion’ in the news chronologically you would find 64 of the first 80 articles are devoted to one thing; the return of Sidney Crosby.
It has been 11 months and 14 days since he was last on the ice when he was playing with a concussion he suffered the game before. Upon getting his head jarred against the boards the symptoms were too much (called a “mild concussion” by his coach) and so began his difficult return to play. This incident has been the most covered concussion management/recovery/rehabilitation in history and at times many thought he would not return. Others thought he should have been on the ice faster, regardless he is back.
The most important factor in this case; the emphasis on full recovery before return to play. Many times it was reported that Crosby was 90-95% better, however continued to have some lingering symptoms and he did not return. A strong show of correct management for the best hockey player in the world.
If his issues cause just one kid to stay out longer until their head is cleared, than Sidney Crosby has done the sporting world a “solid” by being open and honest through the process.
Good luck to Sidney tonight, and expect him to play with reckless abandon, otherwise he will set himself up for injury.

Well now we know. He was sensational in the first game of his return. Only 6 minutes to score his first goal, and ending with 2 goals and 2 assists. Good luck to Sid for the rest of the season!
