The Hendrick Motorsports teams of points leader Alex Bowman and two-time winner William Byron were penalized by NASCAR for violations found in the Richmond post-race inspections. The teams of Bowman and Byron will lose 60 series points and five playoff points apiece for illegal modifications to the center area of the car. It was the second time this year that Hendrick Motorsports has been hit with modification penalties.
Nascar will race on the dirt at Bristol Motor Speedway Sunday night.
