Following their heated exchange on and off the track on Friday, NASCAR has placed Tony Stewart and Kurt Busch on probation.
Stewart ran into the back of Busch during practice causing damage to Busch's Dodge Charger. The 2004 champion retaliated by bumping Stewart several times as the two drivers headed towards pit road.
Both drivers were called to the NASCAR hauler where things continued to escalate. According to multiple sources, Busch insulted Stewart during their argument, which led to Stewart throwing a punch.
Since then, both drivers have said that the incident is behind them. However, NASCAR handed down punishments for both drivers, which is a six-race probation.
NASCAR vice president Jim Hunter plans to redefine the term probation and how it is utilized in NASCAR.
