Busch Pole winner Kyle Larson started Sundayâ€™s Monster Energy NASCAR Cup Series race from the rear after his No. 42 Chip Ganassi Racing Chevrolet failed pre-race inspection three times.
Alex Bowman, who qualified 15th, was in a similar position after his No. 88 Chevrolet also failed three times. He also started from the rear.
Both teams also had their car chiefs ejected â€” David L. Bryant on the No. 42 and Austin R. KonetskiÂ with the No. 88.
In addition, both teams will have to serve a 30-minute hold for the first practice next weekend at Kansas Speedway.
Austin Dillonâ€™s No. 3 car also started from the back for having a non-compliant splitter.
