On October 11, 2012, Hendrick Motorsports announced that Earnhardt Jr. would not participate in the race because of being diagnosed with a concussion one day earlier. Instead, Regan Smith, who was supposed to drive for the Phoenix Racing, would replace Earnhardt Jr., while A. J. Allmendinger would be the interim driver for Smith.^[8] Earnhardt Jr. reported that he experienced concussion symptoms after a crash at Kansas Speedway during a tire test on August 29, 2012. He claimed that he had no symptoms before the Good Sam Roadside Assistance 500, but after being involved in the Big One on the final lap, he reported having concussion symptoms that lasted more than three days later, convincing him to see a neurologist, who said that Earnhardt Jr. needed to miss the next two races because of a concussion. It was the first time since the 1979 Southern 500 (the last race his father missed after an accident at Pocono in his rookie season) that a Sprint Cup race did not have an Earnhardt in the field, and the first race in the modern era that did not have a driver from North Carolina in the field, as Scott Riggs, the only North Carolina driver entered, failed to qualify.^[9]

Three practice sessions were held over the course of the race weekend. The first, held on Thursday, October 11, was used to set the qualifying order. The session was led by Denny Hamlin with a time of 28.170 seconds. Mark Martin was second, only .037 seconds behind Hamlin, with Matt Kenseth in third .016 seconds behind Martin. Joey Logano and Gordon completed the top five, while Kyle Busch, Regan Smith, Kasey Kahne, Jimmie Johnson, and Brad Keselowski completed the top 10.^[10]

Qualifying was held after the first practice session. 47 cars took 2 qualifying laps to set the 43 car field. Greg Biffle would win the pole position, setting a track record with a lap of 27.877 seconds, breaking the old track record set by Elliott Sadler in 2005. After being awarded the pole, Biffle proclaimed his excitement during the lap. "I was super excited about that lap because I drove it farther into Turn 1 than I thought would work,"^[11] Mark Martin would claim the outside pole, Ryan Newman claimed the third position, and Chase drivers Bowyer, Johnson, Truex Jr., Kenseth, Hamlin, and Kahne rounded out the top 10.

A second practice was held on Friday, with Greg Biffle leading the pack with a time of 28.867. Kahne, Harvick, Johnson, Martin, Truex Jr., Keselowski, Smith, Newman, and Gordon completed the top 10.^[12] Happy Hour was also held on Friday, led by Kyle Busch.

The race was held under clear conditions with light winds. Pre-race ceremonies began with the Air Force ROTC Detachment 592 from UNC-Charlotte. K-Love CEO Mike Novak then delivered the invocation, followed by gospel group NewSong delivering the National Anthem. At 7:40, Wounded Warrior Project executive vice president Dave Nevins gave the command to start engines. Ryan Newman, Juan Pablo Montoya, Jeff Burton, and Reed Sorenson went to the rear of the field due to engine changes, while Travis Kvapil and David Gilliland went to the back for unapproved transmission changes. The race started at 7:50, with front row starters Biffle and Martin running side by side for the first 4 laps of the race, with Biffle clearing Martin in turn 4. The first caution came out when Chase driver Matt Kenseth had a left rear tire go down, resulting in him spinning in turn 4 on lap 11.

On the lap 15 restart, Biffle continued to lead when David Ragan, Jeff Burton, and Tony Stewart all collided.
