[34] Sauter stated that he was "just riding along" and that he was "trying to mind my business" before the contact with Allmendinger, with the point of impact being "in the left rear quarter panel".

The third caution of the race flew on lap 51 when Trevor Bayne got loose, came down on Kyle Larson and hit the wall in turn 1.

[50] Ty Dillon, who finished third, was unaware of Busch's injury at the end of the race, while also adding that it was coming "to the point now in NASCAR we should have SAFER barriers at a place like this".

[50] Runner-up Chris Buescher echoed Dillon's comments, stating that the sport "needs to be as safe as possible" and that if "it means lining the inside walls as well, it's probably a good idea".

The red flag was displayed for 6 minutes and 42 seconds, as Allgaier's car had spilled a large amount of oil on the race track.
