Simona De Silvestro OK'd to drive

INDIANAPOLIS -- Simona De Silvestro was cleared to drive two days after a fiery crash burned her hands and put her availability for Saturday's Indy 500 qualifying session in doubt.

The 22-year-old Swiss driver was back on the track at practice early Saturday.

She lost control of the car Thursday and it flipped, burst into flames and slid down the track upside down. She has second-degree burns on the back of her right hand and superficial burns on the back of her left hand and nose.

The Indy 500 race is May 29.
