Just after McFadden took the second position away, the red flag appeared with four laps complete when Kelby Watt took a hard flip between turns three and four. Watt was able to exit the car under his own power.
Windom continued to lead until lap eight when McFadden drove under him for the lead. Behind the race for the lead Jack Anderson and Parker Price-Miller started racing for the final transfer spot with Price-Miller taking the position on lap 15.
