Cup series director John Darby said no penalties will be levied, that NASCAR just wants both drivers to understand there are 41 cars on the track that may be impacted by their decisions.
Busch spun Reutimann out early in the race, then later called the incident an accident because Reutimann's car was loose and he couldn't get off the gas.
About 100 laps later, with Busch running seventh, Reutimann slammed his car into Busch's door, forcing Busch into the wall. Busch finished 21st, falling from third to seventh in the standings.
It started a debate of whether a non-Chase driver such as Reutimann has the right to pay back a Chase driver.
"I don't care if you're in the Chase or not," Reutimann said after the incident. "You need to think about who you're running over when you're running over them."
