Two boys from the Toowoomba Grammar school have been hospitalised after two seperate, serious rugby union incidents.
The first incident occurred on July 13, where a year 12 student dislocated a vertebra and fractured a disc after hitting the ground.
The second incident occurred on July 14 and was of a similar nature.
The first student was flown to the Princess Alexandra Hospital for surgery, where he is expected to stay for four to eight pending his recovery.
Headmaster Peter Hauser said representatives from Rugby Australia and Queensland Rugby Union had contacted both families and were assisting with support programs.
