Danica Patrick and Denny Hamlin wrecked during Daytona 500 practice Wednesday.

Patrick's No. 10 Chevrolet sustained enough damage that she was forced to switch to a backup car and will have to start at the back of the field in the second of two qualifying races Thursday. Hamlin's No. 11 Toyota was repairable.

Patrick and Hamlin started the pileup by making contact coming out of turn two. Casey Mears, Michael Annett and Jeb Burton also were involved.

Patrick called it "the nature of pack racing" while Hamlin said "you always have to give a little bit extra room in practice." But neither driver took full blame, with Hamlin calling it a "miscalculation one way or another on one of our parts."
