Doctors have told the family of a White Bluff teenager that there is less than a 1 percent chance he will ever wake up following a traumatic spinal cord injury in a swimming accident last week. 17-year-old Caleb Holman remains in a coma in Vanderbilt University Medical Center after striking his head jumping into a swimming pool on July 4th. His mother, Becky Holman, reports on her Facebook page that EEG tests over the weekend have confirmed brain damage suffered by her son from the injury is so severe, doctors don’t expect him to recover. Doctors warmed Caleb Holman’s body back to normal temperature and stopped the sedation, but his mother reports there has been no change in his consciousness level. An MRI revealed that Caleb’s spinal cord was severed in the accident, which likely has left him a quadriplegic. The Creek Wood High School senior and member of the county’s clay target gunners was swimming at a friend’s grandparents’ home on Joslin Branch Road Wednesday when he was injured. He is the son of White Bluff Police Chief Mike and Becky Holman.
