Joe Graf Jr. had driven the car to a 29th-place finish, six laps off the pace at the end of the Alsco Uniforms 300. But the No. 07 entry was found with just 17 of the 20 lug nuts safely secured in a post-race check, a violation of Section 10.5.2.5.D in the NASCAR Rule Book. The minimum penalty option for such an infraction is disqualification.
Graf was dropped to last place in the 38-car field. The No. 07 SS Green Light entry notched its first-ever win last weekend, with Cole Custer behind the wheel at Auto Club Speedway.
There were no other issues in post-race inspection, confirming the official results and Ty Gibbs’ first victory of the Xfinity Series season.
