Chase Briscoe’s crew chief, John Klausmeier, will miss Sunday’s NASCAR Cup Series race at Atlanta Motor Speedway.
Klausmeier was issued a one-race suspension after the #14 Stewart-Haas Racing Ford had two lug nuts loose or missing in post-race inspection at Road America on July 4. He also was served a $20,000 fine.
Mike Cook will fill-in as Beiscoe’s crew chief for the Atlanta race.
Briscoe has two top-10 finishes in the first 20 races of the 2021 Cup Series season and is 23rd in the driver points standings. He finished 23rd at Atlanta earlier this season.
No other penalties were issued after the Road America NASCAR weekend that also included a NASCAR Xfinity Series race.
