Austin Dillon's tenure atop the NASCAR Nationwide Series standings is likely to be short lived.
Dillon's car failed post-race inspection Friday night following his victory in the Feed the Children 300 at Kentucky Speedway - his first series win. His No. 3 Chevrolet was found to be too low in the rear.
With the win, Dillon took over the series points lead and holds a two-point lead over Richard Childress Racing teammate Elliott Sadler.
However, similiar penalties this season have resulted in a $10,000 fine to the crew chief and a loss of six driver points. If the same occurs here, Sadler will retake the series lead once penalties are announced by NASCAR next week.
