Dale Earnhardt Jr.

Hendrick Motorsports stalwarts Dale Earnhardt Jr. and Jimmie Johnson will start at the back of the field in the Pure Michigan 400 on Sunday.
Earnhardt had to switch to his backup car after a spin and wreck in Turn 2 during NASCAR Sprint Cup practice Saturday morning at Michigan International Speedway.
Johnson's crew changed engines in the No. 48 Chevrolet.
Sam Hornish Jr. also will start at the back of the field because he did not practice in or qualify the No. 22 Dodge.
Practice and qualifying were handled by Parker Kligerman while Hornish competed in a NASCAR Nationwide race in Montreal.
Johnson (No. 48 Chevrolet) is first in driver points and Earnhardt (No. 88 Chevrolet) is fourth.
Earnhardt won the June race at MIS.
