There was some contact with Logano's car that caused the wreck, and Busch was fuming after watching him finish fourth in the race.

Members of Logano's Team Penske crew quickly pulled their driver away when Busch charged.
Officials had to drag Busch away from the mayhem.
He was visibly fuming and had a bleeding cut on his forehead as he addressed Fox Sports.
