The Pittsburgh Penguins have released a statement on Crosby:
"The diagnosis of Dr. Robert S. Bray, a neurological spine specialist based in Los Angeles, is that Sidney Crosby had suffered a neck injury in addition to a concussion. Dr. Bray reports that the neck injury is fully healed.
"Those findings will be evaluated by independent specialists over the next few days. The most important goal all along has been Sidney's return to full health, and we are encouraged that progress continues to be made."
How did Crosby end up discovering the injury? According to Sportsnet, Crosby saw a specialist in Utah where an MRI indicated an abnormality with the two vertebrae at the top of the spine.
He saw the specialist on the advice of none other than New England Patriots quarterback Tom Brady, who's a friend of Crosby.
