RELATED: Post-Bristol playoff watch

NASCAR issued penalties Wednesday to one team in the Monster Energy NASCAR Cup Series and two organizations in the NASCAR Camping World Truck Series for lug-nut violations.

All penalties came after post-race inspections revealed one unsecured lug nut on each vehicle after last week’s events at Bristol Motor Speedway. That included one infraction after Saturday’s Bass Pro Shops NRA Night Race, involving the Joe Gibbs Racing No. 19 Toyota driven by Sunoco Rookie of the Year candidate Daniel Suarez.

Suarez’s crew chief, Scott Graves, was fined $10,000 for the violation. It’s the third time that Graves has been docked that amount since taking the reins of the No. 19 in late March; he was also fined for single-lug violations after races at Pocono Raceway in June and New Hampshire Motor Speedway in July. Suarez finished 15th in the 40-car field at Bristol.

NASCAR also handed out penalties to two Truck Series teams after last Wednesday’s UNOH 200:

The Kyle Busch Motorsports No. 51 Toyota driven by Harrison Burton, who finished 18th

The Copp Motorsports No. 83 Chevrolet driven by JJ Yeley, who finished 19th

Kevin “Bono” Manion, crew chief for Burton’s No. 51, and Richard Mason, who was crew chief for Yeley’s No. 83 at Bristol, were each fined $2,500.
