After the race
Christopher Bell's car failed post-race inspection, disqualifying him from his third-place finish. He was credited as finishing last, also losing his 17-stage points. For the inspection, NASCAR had the team take the shocks off the car so it can be compared to pre-race inspection. The front of Bell's car was "extremely low" and the rear was slightly higher. Bell's disqualification is the second one to occur under 2019's inspection format, following Chastain's disqualification in the truck series at Iowa in mid-June and is the first Xfinity disqualification since 1995.
