On the restart, Brian Scott took the lead from Suárez. On lap 15, the third caution would fly when Derrike Cope hit the outside wall in the tri-oval after he came across the nose of Austin Dillon. During the caution as the cars made their way to pit road, Jeremy Clements decided to come to pit road at almost the very last minute but Landon Cassill decided not to pit at the very last minute and the two made contact near the entrance and turned Cassill around in the process and gave both cars damage. The race would restart on lap 20. Eventually, the race would finally get its first green flag run of over 5 laps and went green for the next 62 laps.
