The statement gave few details of the mishap involving Christopher Schwarzenegger, the youngest of the couple's four children, nor did it say how badly he was hurt. However, the celebrity news website TMZ.com reported the youth was severely injured when hit by a large wave while surfing or boogie-boarding last weekend in Malibu, suffering multiple broken bones and a collapsed lung.

According to TMZ, the boy was initially hospitalized in intensive care, but his condition has since been upgraded. His parents said the boy is expected to make a full recovery. "While it has been a very scary week, Christopher is surrounded by his family and friends," the statement said.
