Contested over 148 laps of the 1.5 miles (2.4 km) oval, it was the second-last race of the season, and was won by Kevin Harvick in a green-white-checker finish.

Austin Dillon, Blake Feese, Kyle Busch and Ricky Carmichael started from the top five; Tim Andrews, Norm Benning and Derek White failed to qualify for the event.

[4] The next morning, NASCAR announced that Busch would remain parked for the remainder of the weekend, including the 2011 O'Reilly Auto Parts Challenge and the 2011 AAA Texas 500.

[6] NASCAR's action mathematically eliminated Busch from contention for the Sprint Cup, though any realistic chance of him winning it ended earlier in the Chase.

While the sanctioning body lifted the parking directive, it placed Busch on probation for the rest of the year, saying that he would be suspended indefinitely if he committed another action "detrimental to stock car racing or to NASCAR" or "disrupts the orderly conduct of an event".
