Scan results for Alex McKinnon confirm a fracture at C4 and C5.
His spinal cord is not severed but the doctors are unsure about the level of spinal cord compromise.
It will be a number of days or weeks until the extent of his injury is known.
Alex’s family have now arrived in Melbourne and are with him, along with Club doctor Peter McGeoch and Club officials.
When there is additional information, an update will be provided.
