Saturday night's Duck Commander 500 at Texas Motor Speedway.

With 40 laps to go in the Duck Commander 500 at Texas Motor Speedway, the field wadded up coming out of Turn 2 after Austin Dillon checked up in front of Jimmie Johnson, who had nowhere to go and tagged him.That set off a chain reaction crash that involved a total of 13 cars -- all three Richard Childress Racing Chevrolets, Brian Vickers, Matt Kenseth, Brian Scott, Clint Bowyer and several other cars.The accident was reminiscent of the multi-car pileups that frequently happen at Talladega and Daytona.
