Massive wreck on the front stretch took out Jeff Gordon, who led the most laps (124), Tony Stewart the pole sitter, plus Carl Edwards, Juan Montoya, Paul Mendard, AJ Allmendinger, Jamie McMurray, Joey Logano, Clint Bowyer.  It appeared that the 24 tapped the 14, and then chaos ensued.   Tony Stewart in post race interview claimed responsibility for the wreck.
