An experienced cowboy was knocked unconscious and suffered possible spinal injuries at the Outram Rodeo yesterday. Cam Billing, of Te Awamutu, was airlifted by the Otago Regional Rescue Helicopter, after his horse reared in a stall as the gate opened for his ride in the open saddle bronc competition. "The horse reared and slammed him into the back of the chutes. It wasn't him getting bucked off that caused the injury. He was injured before he even came out," Fred Doherty, of the Outram Rodeo, said last night.
