Theriault was injured in an incident with BKR teammate Tyler Reddick. After the two trucks made contact exiting the fourth corner, Theriault's truck shot hard into the outside wall head on. A SAFER barrier did not protect the section of wall Theriault hit.
The 21-year-old driver climbed from the car with the help of safety workers and immediately went to the ground beside the truck. He was placed on a backboard and taken to the infield care center. After evaluation at the track, he was airlifted to a local hospital where he underwent a comprehensive CT scan of the upper body.
Theriault was released from the hospital and will follow up with an orthopedic specialist in North Carolina for further treatment.
