The No. 11 Joe Gibbs Racing Toyota was found with one lug nut not safely secured after Denny Hamlin drove the car to sixth place in Saturday’s FireKeepers Casino 400. As a result, crew chief Chris Gabehart was fined $10,000.

After Sunday’s Consumers Energy 400 at the 2-mile Michigan track, the No. 24 Hendrick Motorsports Chevrolet driven by William Byron to 12th place was found with the same infraction in a post-race check. Chad Knaus, No. 24 crew chief, was also fined $10,000.

The penalty report also notes L1-level penalties issued to both Roush Fenway Racing teams before Saturday’s opener. NASCAR officials confiscated the spoilers of both teams and deducted 20 points from both the team owners’ and drivers’ standings from both the No. 6 and No. 17 team, adding on $25,000 fines for each team. No additional penalties were announced Tuesday.

Also noted was an L1-grade penalty served during pre-race inspection for the NASCAR Gander RV & Outdoors Truck Series to the ThorSport Racing No. 13 Ford team. The team and driver Johnny Sauter were each docked 10 points in their respective standings after the discovery of unapproved truck-bed side panels before their Friday race.
