NASCAR announced two penalties from the Darlington race weekend.

Chad Johnston, crew chief on Kyle Larson‘s No. 42 Chevrolet in Cup, was fined $10,000 for having one loose lug nut following the Southern 500.

In the Xfinity Series, Brandon Jones‘ No. 19 team at Joe Gibbs Racing was docked 10 driver and owner points for his car failing pre-qualifying inspection four times Saturday.

JGR will not appeal the penalty.
