Update: Allmendinger moved to rear of field after Nashville tech issues

NASCAR pulled AJ Allmendinger’s car off pit road at Nashville Superspeedway before practice, and the team could face potential penalties next week.

The No. 16 team was suspected of making unapproved adjustments to its Chevrolet on pit road after passing initial inspection. NASCAR required the team to go back through the inspection, where it was confirmed that those adjustments had been made. Once the team fixed the issues to NASCAR’s satisfaction, they were allowed to rejoin the grid for practice and qualifying.

A NASCAR spokesperson said there could be more to come for the team as far as potential penalties are concerned.

Allmendinger enters the weekend sitting 18th in the NASCAR Cup Series championship standings with four top-10 finishes. He is 13 points out of a spot on the playoff grid.

Sunday’s race at Nashville Superspeedway is set for 7 p.m. ET. It is the 14th race of the season.

Update: AJ Allmendinger will drop to the rear of the NASCAR Cup Series field Sunday at Nashville Superspeedway and have to serve a penalty at the start of the race.

NASCAR provided further details Saturday night about the issue with the No. 16 team before practice started, which resulted in the car being sent back to the garage. The car was re-run across the underbody scanning station to confirm the team had made an unapproved adjustment after going through pre-race inspection.

The adjustment was to the splitter area. NASCAR had the team repair the adjustment, and the car was inspected again to confirm its compliance before it rejoined the field.

Allmendinger did practice but was held for 10 minutes. He qualified 17th.

However, additional penalties have been handed down that will see Allmendinger drop to the rear for the start of the Cracker Barrel 400 and serve a stop-and-go penalty after the green flag. The team also lost pit stall selection for the race, and car chief Jaron Antley was ejected for the weekend. Antley also had his hard card confiscated.
