With under 20 laps to go, Justin Allgaier and Cole Custer were side-by-side and made contact, which caused the right front of Allgaier's tire to go down and triggered an accident that collected Taylor Gray, Riley Herbst, Jesse Love and Ryan Sieg, who entered the race the first driver outside a playoff spot and had come back from being two laps down after electrical issues.

"I checked up and I couldn't check up enough for them in front of me," Sieg said. "That's about all I could do."

Sieg entered the race 10 points behind Sammie Smith for the final playoff spot. Sieg left Atlanta 44 points behind Smith, who finished seventh.
