Two teenagers whose fingers were severed during a tug-of-war game at a Southern California school are awake and alert after undergoing surgery.

Los Angeles County-USC Medical Center spokeswoman Rosa Sacca says the boy and girl have stable vital signs Tuesday and their parents are at their bedsides. But she is not able to say whether doctors were able to reattach their fingers.

Authorities say the students were taking part in a lunchtime game at suburban South El Monte High School on Monday and had wrapped their hands around the rope when it snapped, amputating their fingers.

Authorities say the students lost four fingers each on their right hands and the girl also lost the thumb on her left hand.

The school district plans to review its policies regarding tug-of-war games.
