Overview

• NASCAR said Michael McDowell’s No. 71 failed a rescan after struts were reinstalled, revealing an unapproved front‑splitter change.
• Shane van Gisbergen’s No. 88 was cited for a similar post‑inspection adjustment and received matching penalties.
• Both drivers will start at the rear and serve a stop‑and‑go after the green despite qualifying 21st (McDowell) and 24th (van Gisbergen).
• Crew chiefs Travis Peterson and Stephen Doran were ejected and their teams lost pit‑stall selection, with Spire tapping Matt McCall and Trackhouse elevating engineer Chaise Eliason to manage race duties.
• Rick Ware Racing’s No. 51 failed inspection twice before passing, leading to car chief Dave Jones’ ejection and loss of pit choice, and all 12 playoff drivers cleared inspection without issue.
