“Following the wreck at Talladega Superspeedway, the NASCAR medical team has not cleared me to return this weekend at Kansas Speedway,” a statement from Theriault, shared on Twitter [@Austin Theriault], read. “I’ll be handing the keys over to Garrett Smithley this weekend. I know he’ll represent all of us at RWR and Bangor Savings Bank extremely well. I’m looking forward to the rest of the year. this includes highlighting the great work of the Travis Mills foundation when we run with their colors on the car at the season finale championship race at Homestead-Miami Speedway."

Theriault was among the drivers involved in a multi-car crash on lap 163 of the 500 at Talladega Superspeedway on Oct. 14. The nature and extent of his injury(ies) have not been disclosed.
