Brack

DALLAS -- Kenny Brack had surgery on his broken back, his second operation in two days following a terrifying crash in the IRL's season finale.

The driver was in serious but stable condition at Parkland Hospital, Dr. Henry Bock, the Indy Racing League's medical services director, said Tuesday.

Doctors repaired a spinal fracture and fused three vertebrae on Monday.

"Kenny's spine is stable, and he's moving his legs and toes," said Dr. Kevin Morrill, chief neurologist at Parkland. "We will continue to watch him closely over the next couple of days. Kenny is a world-class athlete, and his physical conditioning will really aid him in this situation."

Brack had surgery on his broken thigh and broken ankles Sunday night. He also broke his sternum.

Brack's car spun in the air after it was hit from behind by Tomas Scheckter in the closing laps of the Chevy 500 at Texas Motor Speedway. The car broke apart when it slammed into the 12-foot steel catch fence at the top of the 39-inch concrete wall on the backstretch.

All that was left of Brack's car was the area in which he was seated. Schecketer was not injured.
