From NBC Sports: Steve O'Donnell, NASCAR executive vice president and chief racing development officer, explained the decision in a statement: "After a full review of multiple videos and discussions with both competitors and their respective race teams, we felt Sunday's post-race incident does not warrant any further action. NASCAR was built on the racing that took place on the final lap by two drivers battling for position. The emotions of our athletes run high, and Kyle Busch and Joey Logano are two of the most passionate and competitive drivers in the sport. Both competitors are very clear on our expectations going forward and we will be meeting with them in person prior to practice on Friday in Phoenix."
