David Cone had surgery yesterday to repair an aneurysm in his right shoulder, but neither the New York Yankees nor the doctors who performed the operation would predict when he'll pitch again.
Doctors took a one-inch vein from Cone's upper left thigh and used it to repair two arteries in his right shoulder during the three-hour operation at New York's Columbia-Presbyterian Medical Center.
``The surgery was performed without disturbing any muscles, nerves or veins in the region,'' a hospital spokesman said. ``The shoulder joint itself was not affected by the aneurysm or the surgery.''
