A link to an article on Sidney Crosby's recovery status. There are some good quotes (articles like this one can only help raise awareness about concussions):

'Crosby has visited with leading concussion specialists in Michigan and Georgia, who have concluded the 24-year-old All-Star will make a full recovery from the concussion he suffered in January that cost him the remainder of the 2010-11 season.

'But how long that recovery will take remains unknown.

'"We always knew this was going to be a progressive recovery – based on how he felt," said Pat Brisson, Crosby's agent, in the statement. "With a concussion, there is not a finite recovery period like with a shoulder injury or a knee injury. That's why we've never even set a specific goal for a return date like the start of training camp or Oct. 1 or anything else. He will play when he is symptom free."'
