NASCAR's Auto Club 400 had an ugly ending on Sunday. Denny Hamlin and Joey Logano crashed during the race's final lap, allowing Kyle Busch to win the race, while Hamlin was airlifted to a local California hospital after a single-car, head-first crash into the inside wall.
Logano's day didn't end there, however, as Tony Stewart and Logano were involved in a fight following the conclusion of the race.
Stewart's anger with Logano stemmed from the race's final restart, when Stewart attempted to pass Logano, but was blocked. Stewart had an opportunity to win the race if he was able to pass Logano, but instead finished 22nd, while Logano finished sixth -- despite crashing.
After the race, Stewart ran over to Logano and exchanged words -- and the words escalated into an altercation.
Logano told USA Today after the race that he was simply "racing hard," and that he felt his move to block Stewart was justified.
Logano said he felt the restart could be the difference in the race and he was just racing hard.
"That was the race for the lead," Logano said. "I felt with the 14 coming underneath me, so I had to block him."
Justified or not, Logano's move drew the ire of Stewart -- which resulted in a post-race fight.
