A spate of cars running out of fuel caused a stack up that finally culminated in the dreaded "Big One," the multi car accident that collects several contenders.
Dave Blaney and Aric Almirola got together, hooking Blaney across the track into Juan Pablo Montoya and collected Landon Cassill, Martin Truex Jr., Jeff Gordon, Terry Labonte, Joey Logano, and Carl Edwards. Gordon, the pole sitter, slammed the wall nearly head on but was able to drive his mangled Chevrolet to the garage. It is just the latest stroke of bad luck in a nightmare 2012 season for the four-time series champion.
Montoya, Truex, Edwards, Cassill, Blaney, and Labonte have also been forced behind the wall.
Jeff Burton, Tony Stewart, Kevin Harvick, Trevor Bayne, Bobby Labonte, Kurt Busch, and race leader Matt Kenseth had all run shy on gas and it was likely what caused Blaney to impact Almirola, setting off the lap 141 melee.
With just over 40 laps remaining, Kenseth has reassumed the lead ahead of Marcos AMbrose, Paul Menard, Brad Keselowski, and Greg Biffle.
