Kurt Busch took the lead on the second lap of the AAA 400 at the Dover and led the next 39 laps relatively uncontested through two restarts. Carl Edwards was second at the competition yellow at lap 40, followed by Kyle Busch, Greg Biffle, and Jimmie Johnson.
The competition caution flew because of rain showers that fell overnight at the track. NASCAR customarily schedules the competition yellows in such scenarios.
The two cautions prior were for light rain and a near-spin by A.J. Allmendinger thanks to contact from Denny Hamlin.
Chase contender Dale Earnhardt Jr. broke a sway bar mount under the first caution for Allmendinger's incident and lost significant track position before being able to pit under the yellow for rain. He lost a lap getting the repairs, but recieved the Free Pass back onto the lead lap for the competition yellow.
Point leader Tony Stewart, seeking to win three-straight races for the first time in his career, runs 15th after qualifying 28th.
