Apparently two broken vertebrae, a spinal contusion, and a concussion. Could have been much, much worse.
Even scarier than the collision is the absolutely HORRID level of incompetence displayed by the on-hand KHL medical staff. They basically prop him up and roll him over into the stretcher, don't even bother immobilizing him or use the fucking backboard. Unreal.
Holy shit. The incompetence of the medical staff was pathetic.
