The eagerly anticipated Sidney Crosby update has come down from the Penguins.
You can read it all here. Here's the key point:
An independent specialist contacted to review recent medical tests taken on Sidney Crosby found no evidence of a past or present neck fracture but verified that Crosby is suffering from a soft-tissue injury of the neck, that could be causing neurological symptoms.
Apparently Crosby and Shero will speak to the media at 6:15. EDIT: It will be live on KDKA and TSN.ca.
