As punishment, Kenseth was stripped of 50 driver points in standings, as well as the three bonus points he earned for the win that would have been applied in seeding for the Chase for the Sprint Cup championship. Crew chief Jason Ratcliff was fined $200,000 and suspended six races. Car owner Joe Gibbs also was suspended six races.
