A rash of playground injuries has prompted one Long Island, N.Y. school to ban balls and require teacher supervision for games like tag.

"Some of these injuries can unintentionally become very serious so we want to make sure our children have fun, but are also protected," Dr. Kathleen Maloney, superintendent of Port Washington Schools, told CBS New York.

The ban at Weber Middle School in Port Washington, N.Y. will apply to footballs, baseballs, soccer balls, lacrosse boalls or any other equipment that might harm a child or school friends. Students will be allowed to play with softer Nerf balls.

Rough games of tag or cartwheels will require supervision from a coach, according to the report.

Children without protective gear may experience injuries ranging from bumps and scrapes to head injuries and concussions.
