Two Monster Energy NASCAR Cup Series cars were found with an unsecured lug nut after Sunday’s Apache Warrior 400 at Dover International Speedway.
The Stewart-Haas Racing No. 14 Ford driven to a sixth-place finish by Clint Bowyer and the 12th-place Furniture Row Racing No. 77 Toyota of rookie Erik Jones each had one unsecured lug nut in a post-race check.
Under the rules set forth in the 2017 NASCAR deterrence system, the suggested guidelines for such an infraction is a $10,000 fine.
