NASCAR handed down penalties to a pair of teams following the Monster Energy Cup and XFINITY Series races at Bristol Motor Speedway.
After Martin Truex Jr. drove to an eighth-place finish in Sunday's Food City 500, NASCAR officials found one lug nut was improperly installed on the No. 78 Furniture Row Racing Toyota Camry. The post-race violation resulted in a $10,000 fine for crew chief Cole Pearn -- the least severe among lug-nut penalties.
Following Saturday's Fitzgerald Glider Kits 300 for the XFINITY Series, the No. 22 Team Penske Ford was found to be too low on the left front during post-race technical inspection. Ryan Blaney's second-place finish is now encumbered due to the violation.
