context_page_description: The 2010 AAA 400 was a NASCAR Sprint Cup Series stock car race held on September 26, 2010, at Dover International Speedway in Dover, Delaware. The 400 lap race was the twenty-eighth in the 2010 NASCAR Sprint Cup Series, as well as the second race in the ten-race Chase for the Sprint Cup, which ends the season. The race was won by Jimmie Johnson, of the Hendrick Motorsports team. Jeff Burton finished second, and Joey Logano, who started nineteenth, clinched third.
  Pole position driver Jimmie Johnson maintained his lead on the first lap to begin the race, as A. J. Allmendinger, who started in the second position on the grid, remained behind him. Fourteen laps later Allmendinger became the leader of the race. Chase for the Sprint Cup participants Clint Bowyer, and Tony Stewart were in the top ten for most of the race, but in the closing laps all of them suffered spins or other problems. Afterward, Johnson became the leader of the race, once Allmendinger made a pit stop because of a loose wheel. Johnson maintained the first position to lead the most laps of 191, and to win his sixth race of the season.
context_section_description: Three practice sessions were held before the Sunday race—one on Friday, and two on Saturday. The first session lasted 90 minutes, while the second session lasted 45 minutes. The third and final session lasted 60 minutes. During the first practice session, Ryan Newman, for the Stewart Haas Racing team, was quickest ahead of Carl Edwards in second and Kasey Kahne in the third position. Clint Bowyer was scored fourth and Greg Biffle managed fifth. Matt Kenseth, Kyle Busch, A. J. Allmendinger, Mark Martin, and Jeff Gordon rounded out the top ten quickest drivers in the session.
  
  Forty-five cars were entered for qualifying, but only forty-three could race because of NASCAR's qualifying procedure. Jimmie Johnson clinched his twenty-fifth pole position in the Sprint Cup Series, with a time of 23.116 seconds. He was joined on the front row of the grid by A. J. Allmendinger. Mark Martin qualified third, Martin Truex, Jr. took fourth, and Denny Hamlin started fifth. Tony Stewart, one of the drivers in the Chase for the Sprint Cup, qualified twenty-sixth, while Kevin Harvick was scored thirty-fourth. 
  The three drivers that failed to qualify for the race were Ted Musgrave, Josh Wise, and Jeff Green. Once the qualifying session ended, Johnson said, "This is certainly a step in the right direction for momentum. Last weekend, we ran much better than where we finished. It stinks that we finished where we did, but there is nothing we can really do about it." Mark Martin, who originally qualified third, started forty-second, after having his time disallowed where the right rear shock exceeded the maximum allowable gas pressure.
  On the next morning, David Reutimann was quickest in the second practice session, ahead of Kyle Busch and Kurt Busch in second and third. Juan Pablo Montoya was fourth quickest, and Jimmie Johnson took fifth. Greg Biffle, Clint Bowyer, Jamie McMurray, Jeff Burton, and Jeff Gordon followed in the top-ten. Other drivers in the chase, such as Carl Edwards, was twentieth, and Kevin Harvick, who was twenty-sixth. During the third, and final practice session, Joey Logano, with a fastest time of 23.802, was quickest. Clint Bowyer and Jeff Burton followed in second and third with times of 23.844 and 23.851 seconds. Matt Kenseth managed to be fourth fastest, ahead of Martin Truex, Jr. and Marcos Ambrose. Denny Hamlin was scored seventh, Jimmie Johnson took eighth, A. J. Allmendinger was ninth, and Brad Keselowski.
  During the third practice session, Denny Hamlin and Kevin Harvick collided with each other. Once they both drove to the garage, they were talking out of anger from the comments that Denny Hamlin had about Clint Bowyer's penalty after New Hampshire. Once the argument ended, Denny Hamlin stated, "There really was just a lot of cursing. That's all that was being said. There was really nothing logical being said between the two teams." Richard Childress, the owner of the Bowyer's racecar, commented, "When you're talking about comments, you can't win a pissing match with a skunk. There are two things I've learned. One thing is that. The other is that you don't throw stones if you live in a glass house." Afterward, Robin Pemberton commented about the collision by saying, "They just got together in practice, and that's fine. Sometimes you get together in practice like that."
