Saturday night after the Bank of America 500 race had ended, NASCAR driver Matt Kenseth attacked rival Brad Keselowski.
The fight happened after the drivers' cars apparently made contact during a cool down lap.
According to USA Today, Keselowski drove his car into several other drivers after the race had ended. One of those drivers, Denny Hamlin, was furious and had to be restrained from going after Keselowski.
Then, as Keselowski was walking away, Kenseth "seemingly came out of nowhere and jumped him," USA Today reported. Several crew members had to pull the men apart. All three drivers were competing for a spot in an upcoming race.
