Nick Harrison, crew chief on Ty Dillon’s Number-3 Richard Childress Racing Chevrolet in the NASCAR X-FINITY Series, has been suspended for one race. The team was found to have used an improper spoiler assembly and extension last weekend at Bristol, where Dillon finished seventh in the Fitzgerald Glider Kits 300.

In addition to his one-race suspension, Harrison was fined ten thousand dollars and placed on probation through December 31st for the rules violation – which was discovered during opening-day inspection.
