DES MOINES, Iowa (AP) Sprint car driver Kevin Swindell had a second surgery on his back Monday for two fractures suffered in a crash last week at Knoxville Raceway.
A statement from Swindell's family said ''both surgeries have been successful.''
Swindell is still undergoing tests for a spinal cord injury.
The 26-year-old driver was injured in a crash last Thursday in the lead-in races to the Knoxville Nationals. His car flipped at the start of a heat race.
His family said they realize Swindell has a ''long battle ahead, but Kevin has remained positive throughout the process and is prepared to fight to regain his health.''
Swindell is the son of famed sprint car driver Sammy Swindell. He is a four-time winner of the Chili Bowl Nationals, and has 30 starts on NASCAR's Xfinity Series.
