From the OCR
Starting quarterback Mark Sanchez left USC practice today because of an apparent knee injury.
The junior from Mission Viejo High was taken on a cart from the locker room to be examined. He had a towel over his head and ice wrapped around his left knee.
The severity of the injury is not known at this time.
Jeez I hope it's something minor.
We will have more as it develops...
UPDATE:
Here is a write up from Gary Klein at the LAT.
A witness reported seeing Sanchez doing a carioca shuffle. He then went to throw a football, put weight on his left knee and collapsed.
Sanchez was helped to the trainers' table, where ice was administered and his jersey and shoulder pads were removed. He was then carted to the locker room and was then taken for x-rays.
