INDIANAPOLIS (AP) -- It started with a crash right after the green flag fell. Then things really got chaotic at the Brickyard 400.
Kyle Busch's car sustained significant body damage when he and Sam Hornish Jr. spun on the first lap of Sunday's race, collecting a group of seven cars.
The melee tore up some of the infield grass, creating debris that apparently got caught in the grills of several other cars and
caused them to overheat. Contenders such as Denny Hamlin, Carl Edwards and Brad Keselowski had to make costly green-flag pit stops.
Then Ryan Newman had a flat tire, and Max Papis' car briefly caught on fire.
And it all happened before lap 20.
