Overview

• Officials summoned the No. 16 Kaulig Racing Chevy back to the garage and confirmed unapproved underbody adjustments during inspection at Nashville Superspeedway.
• Allmendinger’s car failed its first inspection, will start at the rear of the field and must serve a stop-and-go penalty after the green flag.
• The team lost its pit stall selection and was held for ten minutes at the start of practice, compounding its on-track disadvantage.
• Car chief Jaron Antley was ejected for the weekend and had his NASCAR hard card confiscated as a signal against rule-bending.
• Despite the setback, Kaulig Racing confirmed Allmendinger will return full-time to its Cup Series program in 2026.
