The incident occurred after the Bojangles Southern 500 at Darlington (S.C.) Raceway. It was sparked after Busch and Newman were involved in a crash on lap 361. Newman’s Stewart-Haas Racing team was upset that Busch nearly hit Newman's team members coming out pit row, where they had neighboring stops.
Tempers flared again when Busch bumped the back of Newman's car after the race. Members of Newman's crew met Busch as he left the vehicle and a shoving match ensued. It caused a NASCAR official to fall onto the hood of Busch's car.
