Scary crash Saturday at Daytona during the Rolex 24. Memo Gidley suffered a broken back and injuries to his left arm and left leg that required surgery after a horrific two-car crash Saturday less than three hours into the Rolex 24 at Daytona International Speedway.

Gidley's spinal fracture is unstable and will require additional surgery, according to a statement released by the International Motor Sports Association on Sunday morning.

Gidley underwent surgical procedures on his left arm and left leg at Halifax Health Medical Center. He continues to be evaluated.

Matteo Malucelli, the other driver involved, was held overnight for evaluation and is resting comfortably.
