The Nos. 12, 22 and 76 Xfinity Series teams were penalized Wednesday at varying severity for lug nut infractions found during post-race inspection at Bristol Motor Speedway, according to the weekly penalty report.
The No. 12 Team Penske Ford (Austin Cindric) and the No. 76 SS Green Light Racing Chevrolet (Spencer Boyd) were found to have three lug nuts not safe and secure during post-race inspection. Per Sections 10.9.10.4 of the NASCAR Rule Book, crew chiefs Matt Swiderski (No. 12) and Jason Miller (No. 76) were fined $20,000 each and will both serve a three-race suspension through Sept. 12. Each team will also lose 35 driver points and 35 owner points.
Cindric finished 14th in Friday’s Xfinity Series race at Bristol, while Boyd finished 25th.
The penalty would knock Cindric from ninth to 10th in the standings, but he still remains above the playoff cutline.
The No. 22 Xfinity Series Team Penske Ford of Joey Logano, who finished fifth at Bristol, also was penalized for two loose lug nuts. Crew chief Brian Wilson has been fined $10,000 and will be suspended for one race.
In the NASCAR Camping World Truck Series, the No. 68 Clay Greenfield Motorsports Chevrolet of Clay Greenfield was penalized for losing ballast on the track. Crew chief (Danny Gill), truck chief (Melvin Burns Jr.) and mechanic (William Guinade) will all serve a three-race suspension through Oct. 17, per Section 20.3.4 of the NASCAR Rule Book. Greenfield finished 20th in the Camping World Truck Series event at Bristol.
Additionally, the No. 88 ThorSport Racing Ford of Matt Crafton was penalized for a lug nut infraction following his eighth-place finish at Bristol. Crew chief Carl Joiner Jr. has been fined $2,500.
