Overview
- Denny Hamlin surged from the back to take the lead with 39 laps to go on Sunday and won the FireKeepers Casino 400 by 11.110 seconds, recording his 63rd Cup victory.
- A Lap 83 restart produced a large chain‑reaction wreck after Carson Hocevar made contact, which heavily damaged Tyler Reddick’s car and resulted in Reddick’s first DNF of the season.
- Chase Elliott and Christopher Bell crashed violently on lap 148, forcing a roughly 20‑minute red flag to repair the SAFER barrier while Bell is being evaluated for wrist and ankle injuries.
- The race set a Michigan Cup record with 11 caution flags and unusually high attrition, and no Ford entries led a lap at Michigan — the first time that has happened there since 1983.
- Hamlin’s win tightens the regular‑season title fight heading to Pocono Raceway on June 14, and NASCAR and teams continue post‑race reviews of the crashes and any possible penalties.
