Approaching the tense last laps of the finale, Alex Bowman, in his first race back after suffering a concussion, collided with Michael McDowell on the back straight on lap 268, which brought out the sixth caution of the race.
All the lead-lap cars duly pitted, with Chase Briscoe first off pitroad. During the caution, a fire erupted under the #Ford of Brad Keselowski as it rounded Turn 4. He was able to safely exit the car as the fire was extinguished.
