Booty update

Quarterback John David Booty underwent back surgery Friday, where Dr. Robert Watkins operated on his herniated disc and also removed a fragment.
The official procedure is called a ``microscopic discectomy'' and usually offers a shorter recovery period than conventional surgery.
``Dr. Watkins made the point that he had to (have surgery) once he saw what was going on,'' USC coach Pete Carroll said. ``It would be a mistake to wait it out.''
Booty's recovery period is projected to be three months.
