 An exception to this rule was in 2013, where the Chase field was expanded to 13 drivers for that season only as the result of the match fixing scandal.With seven laps remaining in the Federated Auto Parts 400 at Richmond International Raceway, Clint Bowyer went into a spin, forcing a caution.After the race, rumors abounded that Bowyer had deliberately forced a caution in an attempt to manipulate the finish of the race so as to help his Michael Waltrip Racing (MWR) teammate Martin Truex Jr. clinch the second of the two Wild Card spots (Kasey Kahne had already clinched the first spot) over Ryan Newman, who had been leading at the moment of caution.
