INDIANAPOLIS — Seven-time NASCAR champion Jimmie Johnson will be one of three cars sent to the back of the Brickyard 400 starting grid.

After qualifying fourth Saturday, Johnson made a rear gear change. Cole Whitt made the same change, also pushing him to the back of the field. Whitt had qualified 34th in the 40-car field.

The third car belongs to Joey Gase, who qualified 38th. He made an engine change.

A fourth driver, BJ McLeod, was sent to the back of the field when series officials tossed out his qualifying time because of a rules violation.

Series officials also announced on a rainy morning in Indianapolis that there will be a competition caution on Lap 20.
