Those damn, pesky violations.
Both Clint Bowyer and Erik Jones’ teams face penalties for lug nut violations found in the post-race inspection, NASCAR.com reported.
Both drivers guided their cars to excellent finishes at the Apache Warrior 400 at Dover International Speedway.
Bowyer, driving the No. 14 Ford for Stewart-Haas Racing had a sixth-place finish, and Jones, driving the Furniture Row Racing No. 77 Toyota came in No. 12.
The violation could be costly, as the NASCAR rule book suggests a $10,000 per team.
NASCAR will announce the official penalties later this week.
