Principal Judy Beckworth said stood by her decision and said the ban would be in place for a week in a bid to cut back the number of injuries to students in the school yard.
"I don't believe this is taking it too far and this is not an overreaction," she said.
"When you have students badly injuring themselves, it would be unacceptable for me not to take action.
"Parents will relate to this - you sometimes need to do these common sense things to get the message through to kids.
"Of course sport and games are an important part of school life and it will be business as usual next week."
Ms Beckworth said recent injuries included a broken collarbone, wrists and concussion.
Bit more understandable really. what the hell are those kids doing. The curriculum-voluntary payments thing is much more concerning
