This year's Union Cycliste International Mountain Bike World Cup is currently happening in Cairns in Australia. During yesterday's action, a fan reportedly jumped on an injured riders bike and tried to tackle the course. The results are grim to say the least and warrant warning if you are not keen on watching bike crashes. The fan is reortedly being treated in hospital for a spinal injury.
